Online conception calculator. Calculation of a personal ovulation calendar

23.12.202027.05.2017

How often does a woman, upon learning that she is pregnant, try to determine the date of conception? Almost always, when sexual activity is regular, and the birth of a child was not planned in advance. The date and month when fertilization occurred is necessary to know, at least in order to determine the exact date of birth. Today, knowing some of the individual characteristics of your body, you can easily determine the date of conception online using a calculator. 95% out of 100, the calculator will indicate exactly the day it happened.

Of course, if you planned for conception in advance, prepared for this day, visited a family planning center, signed up for consultations and kept diaries and calendars of periods and days of fertilization, then you can probably indicate this day with accuracy. And if not? Most often, at a doctor's appointment, girls who did not expect pregnancy are confused about dates and cannot concentrate, indicating the number when sexual intercourse was performed. It is all the more difficult to calculate the exact date of birth of a baby if you cannot remember with an accuracy of one or two days when fertilization took place.

Proven ways to determine the date of conception

At an appointment with a gynecologist who has confirmed that a pregnancy has occurred, you can often hear questions related to the last menstruation. The doctor will definitely ask what dates the last menstrual period took place, when it began, and how long your menstrual cycle usually lasts. Sometimes doctors in order to determine the date of conception use the period of delay in menstruation, but the main one is still their first day. For this, all expectant mothers are recommended to be sure to keep, carefully and regularly prescribing in it the date of the beginning and end of menstruation.

The gestational age is calculated in several ways:

On examination by a gynecologist. The date will be determined very conditionally, since in the early stages you cannot do without additional examinations and knowledge of your individual data and doctor's calculations;
Most likely, you will be taken to an ultrasound scan, where the exact day of conception of the baby and the expected period of pregnancy will be determined. This method is scientifically proven and the most reliable. However, the ultrasound will show that you are pregnant only at 5-7 weeks, not earlier. And the exact date of birth will be set between 9 and 16 weeks. In addition, an ultrasound scan may be mistaken if the development of the child occurs outside the box - the fetus is too small or large;
Date of conception according to the last menstrual period. A very common way of determining in the event that your cycle does not "float", and menstruation begins exactly on certain days. If the break between periods each time shifts in one direction or another by at least one day, then with such calculations it will be difficult to find out the exact date of birth.

Both methods are widely used by doctors to determine the day of conception and set the gestational age. When calculating, it is important to take into account both the individual characteristics of the mother's body and possible deviations in the development of the fetus during gestation. A child may be born prematurely, or may "sit up" in the womb and be postponed.

Determining the date of conception by the menstrual cycle

How to find out the date of conception by the menstrual cycle, if it is stable? Fertilization of a woman's reproductive cell occurs in the middle of the menstrual cycle, therefore, if a girl's periods pass with a cycle of 26 days, then 13 days must be counted from the date of their beginning. Be sure to take into account when calculating the fact that an egg is able to fertilize only within a day, but the life of a sperm in your body is on average one to three days. Even if you remember the day you had sexual intercourse, it may not always coincide with the day of conception.

For more accurate calculations, in cases where you keep a monthly calendar, you can use the online calculator. Having entered only two digits into the necessary cells - the average duration of the cycle and the first calendar day of the last menstruation, we will quickly get not only the date of conception, but also the estimated number of when the baby may be born.

But what if the cycle shifts from time to time by 1-2 days? The date of conception according to the calculator is also suitable in cases where the cycle fluctuates. It is recommended to write in the cell exactly the average number of days between periods, which you can easily determine by carrying out simple calculations according to your individual calendar.

By specifying the date of conception, you can determine the duration of pregnancy and the estimated birthday of the baby. It is not entirely correct when the expectant mother immediately adds 9 calendar months to the day of conception. Carrying a baby in the womb takes 40 weeks, or 10 lunar months, which is equal to 280 days. This common mistake can play a not very good role in the future, when, instead of going to the hospital on the right day, you go out of town to the country house, significantly increasing the distance that will need to be covered in case of contractions that have begun.

The online calculator will help you to accurately calculate the date of conception only if you definitely know when you had your last period. Usually, gynecologists very quickly calculate the approximate date of birth of the child, and then confirm or correct it by ultrasound. As a starting point, doctors choose the starting day of the last menstruation. 280 days are added to this date, and then the approximate period left for ovulation is subtracted - 14 days.

Doctors do these calculations in their heads and very quickly, because they have to deal with it almost every day. For a woman who has learned about pregnancy and quickly wants to determine the day of conception and birth of a baby, such calculations and formulas may seem too confusing. In addition, the first news of pregnancy, if it was not planned in advance, most often makes future parents nervous, and in this state it is very difficult to make accurate calculations.

Take advantage of the offer and determine the date of conception using a calculator. This will help you calculate your baby's date of birth, prepare for that day, and be careful about carrying a fetus throughout the nine months.

Doctor Komarovsky: preparation for childbirth

If your pregnancy has been confirmed, then I congratulate you from the bottom of my heart on this bright event. Carrying a baby is a wonderful, unforgettable and special period in a woman's life. And this boundless happiness is not given to everyone - remember this always!

Nothing beats carrying and giving birth to a baby. And no life problems, difficulties and troubles can exceed the significance of this event. Therefore, I can't even imagine why a woman needs to know with certainty the day on which conception took place. Nevertheless, many of us are trying to determine the date of conception of a child, and it must be admitted that this is quite difficult to do.

How to determine the day of conception?

Calculating the exact date of conception, if it has already taken place, is simply unrealistic. It is only possible to determine the probable day of conception of the child, but this date will never be 100% correct. This is because, in fact, conception can take place only during ovulation. And if you are not calculating ovulation every month for a long period, you can only approximately calculate the days on which it could take place in the last cycle. To do this, subtract 14 days from the date on which, according to your assumptions, the next menstruation should begin. It is believed that ovulation occurs on average 14 days before the start of the next menstruation: with a 28-day cycle, it occurs on the 14th day of the cycle, with a 30-day cycle, on the 16th, with a 24-day cycle, on the 10th, and so on. Further. But this is a very conditional landmark.

More or less accurately, the date of conception can be determined by the specialist conducting the ultrasound examination. He will tell you the approximate gestational age, which also cannot be considered unmistakably correct.

The fact is that ovulation can be influenced by a large number of different factors that are not able to take into account any of the known methods of calculating the date of conception and childbirth.

How to determine the day for conceiving a child?

If you are trying to determine the most probable or, then everything is much simpler here. To do this, you need to calculate with maximum accuracy the day on which you ovulate. There are many different ways to do this:

basal temperature: Ovulation occurs after a temperature depression, observed a day before the release of the egg from the follicle (there is a decrease in BT by 0.1-0.2 degrees). Then, after the onset of ovulation, the indicators increase by 0.2-0.5 degrees and exceed 37оС;
by the nature of vaginal mucus: Before ovulation, the vaginal discharge is sticky and transparent in the first phase of the cycle, like an egg white. The release of a mature egg may be accompanied by damage to the blood vessels, which a woman observes with minor blood impurities in the vaginal discharge in the middle of the cycle;
for ovulatory syndrome: some women with hypersensitivity may feel pulling pains from the active ovary and even complain of short-term malaise during this period;
via: works on the same principle as a pregnancy test, only unlike the latter, it reacts to an increase in the concentration of the so-called fertility hormone (LH - luteinizing hormone);
by folliculometry: the process of maturation of the egg is carried out by ultrasound, which allows you to accurately determine the day of ovulation.

In addition, an experienced gynecologist is able to determine the approximation of ovulation quite accurately while examining a woman on a chair.

The most reliable result can be obtained by combining several methods at once.

A few days to conceive

Finally, we note that, even knowing the exact date of sexual intercourse that caused pregnancy, it cannot be said with certainty that it is also the date of conception of the baby. After all, the path of sperm to the egg can take more than one day. Moreover, a sperm that has already arrived at its destination can wait for the egg to leave the follicle, if this has not happened yet. Therefore, experts say that, theoretically, the conception of a child can take place as a result of intercourse carried out a few days before ovulation and a day or two after it.

Thus, you cannot quite accurately determine the day of conception of a child, but you can look forward to his birth and become the best mother in the world for him! Is there something more important?

Happiness to you!

Especially for Elena Kichak

Do you already know that you are pregnant? It's fine! But sometimes women have a completely logical question: when did conception occur? And this question arises far from out of curiosity, but in order to determine the expected date of childbirth as accurately as possible. What does the expectant mother need to know for this?

Calculating the day of conception

In order to determine the date of conception, you need to know two dates. The first is the first day of the last menstrual cycle, and for the second it is necessary to analyze the day. When there was sex. These two dates must be set as early as possible, because they can be forgotten very quickly, because a little later all thoughts will be occupied by a rather fast birth and a baby.

Then you can start calculating. The normal gestational age is considered to be 280 days from the moment of conception. Alternatively, 40 weeks or 10 months. Sometimes the question may arise why 10 months, and not 9. such a number due to the fact that usually the beginning of pregnancy is usually called the first day of the last menstruation. Although if you know exactly the date of conception, then the calculations are quite simple.

Probably many women asked the question of why gynecologists consider only from the first day of menstruation. Namely, girls in most cases do not remember when the last sexual contact was, and the whole secret lies. Although sometimes another equally interesting question arises when a girl tries to find out who is the father of her child. Such silly situations arise when there are several sexual partners.

But sometimes women make it easier for themselves to set the date that way. That they keep a special calendar where they mark their periods. So, you remembered when you had the first day of your last period. Then everything is very simple: you need to add 40 weeks before this date. Or, on the contrary, subtract three months and add 10 days. The day and month that you got as a result will be the expected date of your baby's birth.

Calculator to determine the day of conception

If your menstrual cycle is 28 days, add two weeks to the first day of your last period. After all, it is in the middle of the cycle that ovulation and conception of a child occurs. But if your cycle is a little longer (30 days), then conception most likely occurred on the 15-16th. It is also interesting that most women believe that conception took place on the very day when there was direct sexual intercourse. But this opinion is somewhat erroneous, because in some situations the sperm can reach the egg for five days. This is influenced by the quality of the sperm and how mature the female cell is. Also known. That at the same time the egg is attacked by approximately 500 million sperm, of which only one can fertilize it.

It is very important to know the approximate date of conception, because then you can find out the date of birth in order to prepare for them as much as possible. In order for the calculations to be more accurate, in addition to the medical assumption, you can use various online calculators. Calculate now using the online conception calendar.

But at the same time, it is worth remembering that it is unrealistic to calculate the exact date of birth. Only a small percentage of women give birth at the time prescribed by the gynecologist. After all, a child can be born both at 38 weeks and at 42. And this will be considered quite normal and does not go beyond. But still it is better to know at least approximately when the baby can be born and start preparing in advance for his arrival.

If you want to know how to calculate the due date, then this is where you will find the answers to all your questions about this. You can calculate the date of birth by the date of conception, as well as by the last month. If you have access to the Internet, then you can calculate the moment of the birth of a child online for free.

If you do not really trust the online calculator, you can calculate the approximate date of birth yourself, guided by special formulas. We will also talk about them in this article. The exact date of birth is difficult to calculate, since the child himself decides when he will be born. So let's talk about everything in order. How can the date of birth be calculated so that it exactly coincides in the future with the birth of the child.

Due Date Calculator

Determining the due date: What are the ways to determine the approximate due date?

So, you took a pregnancy test and it came back positive. Now we calculate the moment the child is born. The date of birth is counted differently. There are several ways. We will talk about all of them. Let's first list the possible options for calculating the approximate date of birth. Here they are:

you can determine the date of birth both online and without the Internet by the date of conception;
you can calculate your due date from your last menstrual period.

Both of these methods can be used together. They are not mutually exclusive. The most correct option for calculating and calculating the upcoming birth and gestational age in weeks, as well as the size of the fetus, is, of course, ultrasound diagnostics. With the help of it, gynecologists determine the most accurate moment of the birth of a child. He will also determine whether you yourself will be able to give birth or you will need to do a cesarean section if the size of the fetus is large or the baby is lying incorrectly. He will explain and who assigns and pays the woman childcare benefits during maternity leave (employer or FSS). But we will talk about those methods of determining the due date and gestational age, for which you do not need to leave the house and even get up from your favorite couch. After all, you can find out everything using the Internet.

How to calculate childbirth by date of conception?

To calculate the expected moment of birth of the baby by the date of conception and determine the gestational age in weeks, you need to have a regular menstrual cycle and know when ovulation has occurred. After all, conception is possible only during ovulation. Well, we are not even talking about what else you need to remember the day on which there was an intimacy with your loved one. It's obvious. If, for example, most women have 28 days of menstruation, then ovulation usually occurs on days 14-15.

But it is worth noting that the conception of the fetus might not have occurred on the day of sexual intercourse. It has been noticed that sperm cells are able to live even 3 days, while “walking” inside a woman. Therefore, here the approximate moment of birth of the fetus by the date of conception will be determined approximately, and not day to day. The error may even be one to two weeks. So, now you need to add 280 days to the day of conception (this is exactly how much pregnancy lasts on average for most women). So you will calculate and determine the date of birth by conception and the gestational age in weeks. It's pretty simple if you have a regular menstrual cycle and a good memory.

If you do not want to bother yourself and want to immediately determine the day of your birth by conception and the duration of pregnancy in weeks, then use a special calculator on our website. Here it will be enough just to enter the estimated day of ovulation in the table and click the "Calculate" button. The computer will calculate and display the pregnancy period in weeks and the due date. As a result, you will find out when the child will appear and will look forward to this day and will no longer look for the answer to the question "How to determine the date of birth by conception." This is a kind of fascinating fortune-telling that gives out the correct prediction.

How to calculate the exact date of birth by menstruation and find out what week of pregnancy you are?

To make a calculation and find out the most accurate date of birth by menstruation, that is, find out when a person is, you should also have a regular menstrual cycle. The formula for calculating the moment of birth of a child based on the last menstruation of a pregnant woman is used by all gynecologists in their practice. They will certainly ask the expectant mother who came to see them about the first day of the last menstruation. There are probably no such pregnant women who were not interested in the first day of the last menstruation by gynecologists.

So, we calculate the approximate birthday of your child and find out how to determine the date of birth by the last menstrual cycle (by its first day). In order to start calculating the preliminary day of childbirth, from the first day of the last menstruation, you must count three months ago, and then add seven days. So it turns out the approximate day of birth of a child.

If you don't want to count in your head, you can calculate the moment of the baby's birth using an online calculator, which, after entering the data, will give you the due date and what week you are automatically. To do this, simply enter the first day of the last menstrual cycle in the special window of the calculator, as well as the average duration of menstruation and the duration of the luteal phase (for most women, it lasts two weeks, that is, 14 days). Then press the "Calculate" button and wait for the results of the online test. Almost every woman used this calculator. It is popular nowadays.

Now you know how to calculate the due date, a calculator will always help with this. And also, finding out the length of your pregnancy in weeks and even days is no longer a problem for you either. We hope that you will make the calculation correctly and without much difficulty and with great pleasure, and in the future make sure that the actual day of birth of the baby coincides with the one given by the calculator! In the future, the question "How to determine the date of birth online" you will not have. About how to determine the date of birth by ultrasound and fetal movements, as well as how to bring the date of birth closer and get pregnant using IVF, read other articles on our website.

Pregnancy is the most important stage in the life of any mother. The health of the unborn baby depends on the preparation for it and its course. To determine the exact term of pregnancy and childbirth, the date of the fertilization that took place is important. There are several ways to determine the date of conception, it remains only to choose the most optimal one.

It is well known that a woman can become pregnant only during the ovulatory period. During these hours, a female cell ready for conception leaves the ovary in the direction of the uterus. The life span of the egg is short and rarely exceeds 36 hours, so the chances of conceiving a child within one cycle are negligible for spouses. When sperm enter the vagina, under the most favorable conditions, a tiny fraction of them can live there for about a week. That is why the process of conception can take place several days before and on the day of ovulation. How to determine the day of the fertilization that occurred?

With one intercourse, about 500 million sperm enter the vagina, which modestly accumulate at the posterior vaginal wall near the uterine cervix. For conception to occur, the sperm must get to the mature egg in order to properly fertilize it. For this, the sperm has a rather difficult path:

First, it passes 2 cm of the cervical canal;
Then it overcomes 5 cm of the uterine cavity;
Then his task involves overcoming 12 cm of the fallopian tube.

Only after passing the cherished 19 cm does the sperm get to the meeting place - the ampullary section, where the "meeting" with the egg takes place. It takes about three hours for sperm to overcome this path, and the female body resists this process in every possible way. In fact, the vagina is an aggressive environment for sperm cells, in which most of them die. During the period of being in the vaginal environment, the sperm dies after 2 hours. Therefore, a sufficient number of viable and active sperm is essential for fertilization.

Process features

Many of the sperm cannot reach the egg, entangling themselves in the epithelial layer of the fallopian tubes. But they can wait for the release of the egg here, since they can live here for about 5 more days. At the same time, conditions favorable for fertilization at 37 ° C are created at the meeting point of sperm and egg cells. But getting to the egg is not enough, you still need to break through its protection. This is also taken into account by nature, therefore, a specific enzyme is present in the head of each sperm, which dissolves the membrane membrane of the egg. When one sperm manages to fertilize a female cell, the composition of its membrane changes so that no more sperm can get inside, which die within 48 hours.

The egg enters the uterus about the fourth day after fertilization has occurred. It takes another three days to attach, after which the conception can be considered completed. It is at this time that chorionic gonadotropin begins to actively enter the bloodstream, which is determined by express pregnancy tests.

When conception took place

To determine the day of conception, it is necessary to accurately calculate the ovulatory period, then compare it with the date on which unprotected sexual intercourse took place. Usually, conception occurs in the middle of the female cycle. Therefore, with a monthly cycle of 28 days, you need to count from their beginning 14 days. During a similar period, the ovulatory process and conception occur. When calculating, it is imperative to take into account that sperm will be able to fertilize a female cell only within a day and a half, but sperm survivability can persist up to 5 days (in some, up to a week). Therefore, even knowing the number of sexual contact that has occurred, one should not expect that it will coincide in date with conception.

There are two types of gestation periods - true or obstetric. The true or specific period is counted from the ovulatory period and the moment of fertilization. He usually lags behind obstetric by about half a month. The obstetric period can be calculated based on and comparing certain factors, such as the onset of maturation of the female reproductive cell, the formation of the ovum and the formation of the fetus. This calculation starts from the date the last menstrual bleeding started.

Proven ways to calculate dates

There are other proven methods for determining conception. After confirming the fact of pregnancy, the obstetrician asks each woman at a gynecological appointment in detail when the last menstruation began, the duration of the cycle and other information of this kind. Some doctors, in order to determine the exact date of conception, are guided by the duration of the menstrual delay, although the main starting point is still the day of the beginning of menstruation. Therefore, women are advised to keep a female calendar, in which you need to enter all the information regarding the beginning and end of menstruation. There are several proven options for how to find out the date of conception.

With the help of a gynecologist. This period and date of fertilization will be very relative, in order to more accurately determine the date of conception of the child, additional examinations and medical calculations are needed.
Calculate the term for the last months. This is a fairly common technique, but it is applicable only in the case when the cycle is constantly the same, does not float and does not get lost, menstruation constantly comes on a certain day. In cases where the cycle is constantly shifting by decreasing or increasing days, it will be difficult to calculate when exactly delivery will occur.
When registering, each woman is sent for ultrasound diagnostics, where the date of conception is determined, as well as the gestation period. The ultrasound method is the most reliable, only such a study will be able to show the presence of pregnancy only for a 5-7-week period, not earlier. But you can find out when the baby should be born with the help of ultrasound diagnostics in the period of 9-16 weeks. If the fetus develops with deviations (too large or small), then the ultrasound can give erroneous calculations.

These methods are used by gynecologists to identify the exact day of conception and to establish the timing of fetal development. In the process of calculations, it is necessary to take into account the individual characteristics of the mother's body, the presence of probable deviations in fetal development, etc. Also, do not discount the fact that the newborn will be active to be born a little earlier than the calculated time, or, conversely, will stay in the mother's womb even for a week.

Calculator

So, in order to determine when conception took place, you need to have information about two dates: the first day of the last menstruation and the days when there were intercourse without contraception. It is recommended to write down these dates, because, as practice shows, they are forgotten quite quickly, and it is difficult for a woman to remember when the last bleeding was already at a gynecological appointment. How to find out the required date, knowing the above numbers?

Normally, the duration of gestation is 280 days from the day of conception. It's 10 months or 40 weeks. So, you know the start date of the last menstruation. Add exactly 40 weeks to this number. The resulting result will be the number when the baby is supposed to appear.

If you need to determine the date of conception of a child, then everything is also simple here. Ovulation occurs in the middle of the menstrual cycle. With its duration of 30 days, fertilization will occur on 15-16 days. It is a mistake to say that an egg is fertilized on the day of sexual intercourse. Sometimes it takes several days between sex and conception, depending on the degree of maturation of the egg, the viability and mobility of the sperm.

What gives the knowledge of the date

Knowing when conception occurred is important in order to calculate the time of delivery. In addition, such information will help monitor fetal development. Every week, specific changes occur with the fetus, in order to find out whether this is the norm or a deviation, it is necessary to reliably determine the gestation period. This will help control the growth and development of the fetus, determine whether the pregnancy is proceeding favorably, etc.

In addition, knowing the exact day of conception, you can find out the exact date of birth, determine the time of mom's maternity leave, etc.

Period of conception

It has already been noted that even with the exact date of sexual intercourse that led to the onset of pregnancy, this day cannot be considered with absolute certainty the date of conception. Since sperm cells can reach the female cell for several days, conception can also be determined by several days, covering the ovulatory period. When patients are interested in how to determine the dates of conception, doctors usually say that conception can take place after sexual intercourse, which occurred a few days before the ovulatory period and a couple of days after its end.

In obstetric practice, it is quite rare that childbirth occurs at the appointed time, because a newborn may not be born at 40, but at 42 or 38 weeks, which is not a deviation. Therefore, the preliminary date of birth should be treated as a rough guideline.

The term "ovulation" itself comes from the Latin ovum - egg; so called the process of release of a mature, capable of fertilization of the egg from the ovary into the abdominal cavity.

Physiologically, ovulation is one of the stages of the menstrual cycle. Ovulation in women of childbearing age occurs periodically, every 21 to 35 days - in the middle of the menstrual cycle (the cycle is usually counted from the first day of menstruation). The frequency of the onset of ovulation is regulated by the hormones of the pituitary gland, the endocrine gland located in the brain, and the hormones of the ovary (estrogen and progesterone). Ovulation stops with the onset of pregnancy and after the extinction of menstrual function.

For sexual intercourse for the purpose of conception, the most favorable moment is when ovulation is about to occur and the sperm have enough time to enter the fallopian tubes, where they "wait" for the release of the female germ cell, or immediately after ovulation, when the egg is already in fallopian tube.

Day of conception

If you correctly calculate on what day ovulation will take place, and during this period of time to have sex, then there is a high probability that a woman will become pregnant.

So how can you determine ovulation? First of all, with the help of subjective signs. It can be short-term pain in the lower abdomen, a feeling of a "bursting bubble" in the middle of the cycle, some women note an increase in libido - this is due to the release during ovulation of estrogens - female sex hormones that are produced in the ovaries. Some signs can be detected during a routine gynecological examination, although it is difficult to imagine that a woman who believes that she does not have reproductive problems will turn to a gynecologist only to determine ovulation. However, a woman can notice a number of signs herself.

The day of ovulation can be determined by observing the secretion of mucus from the cervical canal. The maximum secretion of mucus is associated with a sharp increase in estrogen levels and coincides with the time of ovulation. In addition, the extensibility of mucus is sometimes used, and its crystallization is also observed. During ovulation, mucus becomes very stringy, it can be stretched between the fingers up to 8-10 cm. The more pronounced the crystallization, the more likely ovulation. This phenomenon is most pronounced 3-4 days before ovulation and reaches its maximum on the day of the expected ovulation. Crystallization is the result of biophysical and biochemical changes in cervical mucus. During this period, there is an increase in the amount of mucus and an increase in the concentration of salts, primarily sodium chloride, which, along with potassium ions, is responsible for the crystallization phenomenon. With pronounced crystallization, the mucus looks like a fern under the microscope. There are special microscopes for home use on which mucus or saliva can be applied. The main changes occur precisely in the vaginal mucus, but they also affect the entire body, therefore, for convenience, they began to work with saliva, in which it is also possible to determine the symptom of crystallization. This phenomenon is based on the operation of the device for determining ovulation "Baby-Plan".

The next most accurate and informative method for determining ovulation is the measurement of basal temperature - the temperature in the rectum. The method is quite simple and does not require almost any special equipment, except for an ordinary medical thermometer.

The basal temperature is measured with the same medical thermometer in the morning, immediately after waking up, without getting out of bed. The measurement must be carried out at the same time, introducing a thermometer into the anus to a depth of 4 - 5 cm. Temperature measurements are plotted on a graph, the vertical axis of which is the temperature, and the horizontal axis is the day of the menstrual cycle. The graph also shows the days of sexual intercourse.

In many women, with careful monitoring of the basal temperature graph, it can be revealed that there is a short drop in temperature before the temperature rises. According to this method, it is believed that the moment of ovulation occurs 12 hours before the increase in basal temperature or between the decline and the beginning of its rise.

Can I choose the gender of the baby?

When planning a pregnancy, few potential parents do not think about how to choose the gender of the unborn child in advance. Some need a boy, others a girl. Such planning becomes especially relevant when the family already has one child. As a rule, parents dream of having a second baby of the opposite sex.

There is only one more or less scientifically sound way to try to schedule the sex of the baby. A sperm with a male set of chromosomes moves faster, but lives less than a sperm with a female set. Therefore, the coincidence of sexual intercourse with ovulation (approximately 14 days before the onset of menstruation with a 28-day menstrual cycle) increases the likelihood of having a boy, and the birth of a girl is more likely if intercourse occurs 2-3 days earlier. However, this rule does not always work, since it concerns the classic situation of "superhealthy" parents in all respects. If any of the partners have deviations in health, this, as a rule, affects the "speed characteristics" of the sperm. For example, this happens when the acid-base balance of the genital tract is disturbed or the qualitative composition of the secretion in women changes, or when men are physically fatigued (it also affects the mobility of "lively").

But all these listed methods give only approximate results. Their accuracy allows you to determine the moment of ovulation only using all of them in a complex and with a fairly long observation. What makes it possible to establish the moment of ovulation accurately and guaranteed to document it? There are, strictly speaking, only two such methods.

The first is the ultrasound observation of the growth and development of the follicle - the bubble in which the egg matures, and determining the moment of its rupture - the actual ovulation. Often, when using modern devices, it is possible to see even the very moment of the release of the egg, if the study is carried out at the right time.

The second method is the dynamic determination of luteinizing hormone in the urine (it is also an ovarian hormone, the amount of which increases during ovulation). This method is much simpler and can be applied at home, for which special tests are used. The tests begin to be carried out 2 times a day (every 12 hours) 5 - 6 days before the expected ovulation, strictly following the instructions attached to them. The determination is stopped after the first positive result is obtained. Ovulation occurs approximately 16-28 hours after the first positive test result. Another test can be performed immediately for control. The most convenient and informative use of tests for luteinizing hormone in conjunction with measuring basal temperature. Dynamic determination of luteinizing hormone was previously used only in specialized medical institutions, but now there are test strips, the same as for determining the short term of pregnancy. These tests are sold in pharmacies. Thus, the task of determining the moment of ovulation should be recognized as practically solved.

I must say that if there are no alleged problems with conception, then you can start with a simpler method - calculating your ovulation based on the duration of the menstrual cycle. To do this, as we have already said, the duration of the menstrual cycle must be divided in half. To start "working" on conception, taking into account the fact that some sperm live up to 7 days, a favorable period will end 3 days after ovulation a week before the expected ovulation.

Keep in mind that pregnancy may not occur immediately during the first "dangerous" period, because even healthy young women have 1-2 cycles per year in which ovulation (release of an egg) does not occur.

In addition, stress, climate change, etc., affect ovulation.

Conception pose

After you have calculated the days, the most favorable days for conception, you must give up douching, any soap and similar products after intercourse. Firstly, the very fact of washing contributes to the mechanical removal of sperm, and secondly, hygiene products create an environment in the vagina that is unfavorable for sperm. Yes, and before intercourse, you should take a shower ahead of time (30-60 minutes) so that a normal, natural environment can be restored in the vagina.

Couples looking to conceive often ask themselves: is it worth using a special pose? It's safe to say that any pose that is acceptable to both partners will do. After sex, it is better to lie down for 15-20 minutes on your side or with your pelvis raised to prevent sperm from leaking out.

We hope that our tips will help you transition to the parent-to-be category as soon as possible.

Menstrual cycle

There is a widespread misconception that a woman's menstrual cycle should last exactly 28 days, and ovulation should occur exactly "on the 14th day of the cycle" or "in the middle of the menstrual cycle." This is not true.

In fact, the menstrual cycle is divided into two phases - follicular (before ovulation) and luteal (after ovulation).

Follicular phase

The follicular phase (preceding ovulation) begins on the first day of the last menstrual period and lasts until one dominant follicle (or several) matures in the ovaries. Ends with ovulation.

Luteal phase

The luteal phase (corpus luteum phase) begins from the moment of ovulation and lasts about 12-16 days.

In place of the ovulated follicle, a corpus luteum forms within a few days after ovulation. Its main function is to synthesize progesterone and estrogen to support future pregnancy. If pregnancy does not occur, then after 10-12 days the corpus luteum undergoes reverse development, which leads to a drop in the level of hormones, after which the next menstruation begins. If pregnancy has occurred, the corpus luteum continues to function and support pregnancy.

In the absence of pregnancy, the level of progesterone reaches its maximum value about a week after ovulation - at this time it is recommended to take a blood test for progesterone to assess the function of the corpus luteum.

Length of the menstrual cycle

The follicular phase can vary in duration (both for different women and for one woman throughout her life). Usually, the length of this particular phase of the cycle determines the length of the entire menstrual cycle and affects the delay in menstruation - for example, if the maturation of the follicle occurs faster or slower than usual, or does not occur at all. The luteal phase is usually of a constant duration (12 to 16 days).

Baby gender

The gender of the unborn child does not depend on the location of the stars in the sky, the menu of the future parents or the posture at conception. The gender of the child depends on which type of sperm will fertilize the egg - the one carrying the male Y chromosome or the female X chromosome. Spermatozoa of the "male" sex, as a rule, move easier and faster than the "female" ones, but they are more sensitive to external conditions and adverse influences. Spermatozoa of the “female” sex, on the contrary, are less mobile, but more hardy. Thus, if intercourse occurs on the day of ovulation or later, the likelihood of having a boy increases, and if intercourse occurs long before ovulation, then the likelihood of having a girl increases and the likelihood of conception decreases. However, experts believe that the reliability of this method does not exceed 60%.

One of the deciding factors for women planning a pregnancy is their menstrual cycle. Timing to have sex with your partner on certain days of your menstrual cycle during ovulation can greatly increase your chances of getting pregnant. Before calculating the most favorable days for conception, you need to better know the features of your cycle and learn how to properly track it.

Steps

Part 1

Understanding the menstrual cycle

Identify the key stages of your menstrual cycle. The menstrual cycle has several stages, but this does not mean that you can conceive a child throughout the cycle. The assumption that a woman can get pregnant at any stage of the menstrual cycle is a myth. The truth is that you can only get pregnant on your fertile days, before and after ovulation. Ovulation occurs when a mature egg leaves the ovary and travels down the fallopian tube, whereupon it is fertilized by a sperm. The phases of the menstrual cycle are as follows:

Identify auspicious days for conception. This is the period of your menstrual cycle when you are more likely to get pregnant after intercourse. For most women, the favorable period for conception lasts about six days.

Remember that intercourse on favorable days does not guarantee 100% pregnancy. But your chances of getting pregnant will be significantly increased if intercourse occurs within 5 days before ovulation and 24 hours after. Healthy young couples generally have a 20–37% chance of getting pregnant using this system.

Determine if you have a regular menstrual cycle. Every woman has a different menstrual cycle, which can change due to external factors such as stress. The best way to determine if you have a regular cycle, that is, how closely each subsequent cycle matches the previous one, is to trace its duration over three to four months.
- Mark the first day of your period on a calendar. Mark it as Day One. Then count down the days until your next menstrual cycle. Remember that the average menstrual cycle lasts 28 days, but it can also last from 21 to 35 days.
- Do this for three to four months. Note the difference in the length of each cycle.
Pay attention to the irregularity of the cycle. You may have an irregular cycle if after three to four months of tracking your menstrual cycle, you have not noticed regularity. This happens to many women and can be attributed to a number of factors, such as sudden weight loss, increased physical activity, stress, or serious health problems. Check with your doctor if you have an irregular cycle to find out if you have a serious medical condition. Women with irregular cycles can still determine the most fertile days, but it just takes more time and effort than women with regular cycles.

Part 2
Determination of favorable days for conception
1. Use the length of your menstrual cycle to determine the most fertile days for you. If you have a regular period, you can determine fertile days by tracking the length of your menstrual cycle. The most favorable days for conception will be six days before and during ovulation. But the most favorable days will be three days before and during ovulation. Use the length of the menstrual cycle to determine the most favorable period for conception, counting 14 days from the total duration of the menstrual cycle:
2. Check your body temperature or use an ovulation tracking kit if you have an irregular menstrual cycle. If you have an irregular cycle or think you may have a broken cycle, use other methods to track your ovulation days:
  - Monitor your body temperature. During ovulation, the body temperature rises. Check to see if you have a "thermal shift" by measuring your temperature at the same time every morning. Most women have a half-degree deviation in body temperature 24–48 hours after ovulation. You can use a regular thermometer or buy a basal body temperature thermometer.
  - Buy a kit to measure your ovulation period. Look for these at your local drugstore. While this is more expensive than taking your temperature, it can help you more accurately determine when you are ovulating. This kit will test your urine and determine the level of luteinizing hormone (LH) in it. You will need to urinate on the test sticks to determine when the hormone will rise. This is a sign that one of your ovaries is about to release an egg, or that you are about to ovulate.
  - Watch for changes in the mucus secreted by the cervix. Before ovulation, your body will begin to expel large amounts of thin, clear mucus secreted from your cervix. This substance helps the sperm get into the egg. Just before ovulation starts, you will notice mucus on your underwear or around your vagina. It will be transparent, viscous and slippery, like the white of a raw egg. You can collect a sample of cervical mucus by lightly rubbing the vaginal opening with a piece of tissue or a clean finger. If you checked for discharge for one day and did not notice mucus, most likely this is not the most favorable period for conception.
3. Engage in an intimate relationship during the most favorable period for conception. Most doctors recommend having sex with your partner every day or every other day for the five days before ovulation, as well as during the day after. Although sperm live in a woman's body for five days, the life span of an egg is usually 12 to 24 hours, so intercourse before, and during and after ovulation will increase your chances of getting pregnant.
  - Concentrate on sexual intercourse during the most fertile period, or three to five days before ovulation. Do not wait for ovulation to begin, because by the time the sperm enters your body, the egg will no longer be ready to fertilize.
  - If you are under 35 and have had sex on your fertile days in the past 12 months but have not gotten pregnant, or if you are over 35 and have been tracking fertile days for six months without any results, talk with your doctor to assess your fertility. You and your partner may have a fertility test to determine if you have any health problems that might prevent you from getting pregnant.

Pregnancy calculators

Your personal calendar of fertile and safe sex days.

There are three questions this calculator can answer:

When can you not use protection? (calendar method of protection is considered ineffective)

When could you get pregnant? (better ask it to another calculator, it's called "")

When to get pregnant? (this question is the most appropriate)

The appearance of a baby in a family is a significant and very important event; they always prepare for it in advance. And not always from the moment it becomes known about the pregnancy of the expectant mother, planning for the birth of a child, as well as, often occurs long before the onset of pregnancy.

The correct lifestyle that a future mother should lead is one of the prerequisites for the birth of a healthy and full-fledged baby. In addition, for the birth of a healthy baby, it is necessary, before calculating the conception calendar, to undergo a full medical examination, to treat chronic diseases (the same tonsillitis), to visit the dentist, and also to talk with a geneticist. When the preparatory stage is over, and you are convinced that the future parents (yes, and the father too!) Are healthy, you can start ... counting.

How to calculate the conception of a child

The choice of the right moment of conception today is quite simple thanks to modern science, there is a special calendar for conceiving a child - an average scheme that can be guided by when counting. To obtain reliable information and compile an individual conception calendar, automatically calculated by the computer according to the program, you just need to enter your data - the average duration of the menstrual cycle (it is counted from the first day of one menstruation to the first day of the next) and indicate the first day of the last menstrual cycle. The main task of the calendar of conception of a child is to show the most favorable days for conception, when the female body is as ready as possible for fertilization.

Using the child's conception calendar or, you can try to program the sex of the unborn child - geneticists say that the birth of a girl will ensure the conception of a baby before the peak of ovulation. And if you correctly calculate conception and carry it out immediately at the time of ovulation or immediately after it, a boy will be born. You can find out when you are ready to reproduce by using or passing an ovulation test.

A little educational program

The high level of information technology does not necessarily mean that we all fully possess the necessary information. What are the calculations of the conception calendar based on and how safe are “safe days for sex”?

During the menstrual cycle, the female body is ready in different ways to rebuild and allow to settle inside a new life. Those days when full sexual intercourse with ejaculation does not lead to conception are called safe days, and the most suitable days for conception are days when the most active sperm cell is quickly and quite successfully able to fertilize an egg - ovulation days or favorable for conception.

The moment of ovulation is the time when the female germ cells are in "active mode", that is, they are fully ready to perform their functions. This moment comes in the middle of the menstrual cycle and lasts 2-4 days, therefore it is not difficult to calculate ovulation if you know exactly the duration of your cycle. For automatic counting, a special one has been developed, which in a few seconds is able to calculate ovulation and indicate the optimal days for conception.

It should be remembered that each human body is a purely individual mechanism, therefore, you should not fully rely on to count the days for safe sex. Because the concept of safe days existing in the terminology of obstetrics, referring to the topic of pregnancy planning, has an indirect relationship to prevention of unwanted pregnancy. Calculating the calendar of conception in order to choose the days when you can have safe sex without protection is illiterate and stupid, since your body may have “dangerous” days ... at the end of the menstrual cycle (and this happens when the cycle is unstable, and the ovulation time is extended , therefore it fails correctly).

How to get a wonderful person

No one will argue that everything around us affects our condition, attitude, and ultimately, life. But few people think that the roots of this influence are very deep. They hide in the most intimate mystery - the moment of conception. Therefore, if with the help you have identified the most favorable day for conceiving a child, try to turn it into a real holiday - bright, joyful, happy. Even if you are an unbeliever, then let the results of medical research, claiming that even flora responds to beautiful music and plants grow faster, tell you the right way to show your baby that he is wanted, expected and already loved.

No wonder in many languages \u200b\u200bthere is a romantic name for the act of copulation between a man and a woman - making love. Let sex on the day you choose for conceiving a child become not just lovemaking, but the desire to share your love not for two, but for three - you, parents, and your baby. And then, as you wanted, your child will be the smartest, the most beautiful, the healthiest, the best ...
