How to calculate which day to conceive. Favorable days for conceiving a child

Reading time: 5 minutes

Doctors strongly recommend that women mark the beginning of each menstruation on the calendar so that, based on these data, it is possible to calculate the date of ovulation and calculate the term for conception of a child. Not every sexual intercourse results in the fertilization of an egg. For the successful onset of pregnancy in the body of a woman, a number of processes must occur, which will be discussed below.

What is conception time

From the first day of the cycle, the body begins to prepare for pregnancy. Follicles mature inside the ovaries. One is growing faster. At the moment of rupture of the follicle, the mature egg penetrates into the fallopian tube. This process is called ovulation. An unfertilized egg lives for a day. If fertilization does not occur, she dies and goes out with her period. Spermatozoa are more viable. Part dies along the way from the vagina, but those who have penetrated the fallopian tubes wait for the egg for 3-4 days. The term of conception is a period in the middle of the cycle lasting 4 days: three before ovulation and one after.

What gives knowledge of the date

To calculate timing of conception, you need to calculate the date of ovulation. Sexual intercourse should occur no earlier than 4 days, and no later than one day after it. it it is useful to know for those who dream of getting pregnant or, conversely, do not want children. If pregnancy has occurred, it is impossible to accurately calculate the day the child was conceived, but it is possible to calculate when this happened with the highest probability.

How to calculate the date of conception

To calculate favorable dates, you need to determine when ovulation occurs, in the following ways:

calendar method;
measurement of basal temperature;
ovulation tests;
folliculometry.

Any method has an error. Even a healthy female body is not stable. Sexual contact can cause premature release of the egg, and stress and fatigue are the cause of late ovulation. A woman can determine the onset of the ovulatory period by sensations. Indirect signs of the onset of ovulation:

pain in the lower abdomen;
mucous discharge from the vagina;
change of mood;
increased sex drive.

Calculate conception date from last period

Doctors consider the date of conception the first day of the last menstruation. The obstetric period exceeds the embryonic one by two weeks. With an irregular cycle, the difference between them is significant. The advantage of the method is that women know the date of the last menstruation. The calendar method for determining ovulation is suitable for a regular cycle. For several months, enter in the calendar information about the beginning of menstruation. Divide the average cycle time in half. If you add the resulting number to the first day of the last menstruation, you get the date of ovulation.

Date of conception by date of birth

To calculate the day of conception of a child, you need to subtract a week from the preliminary date of birth and add three months. This is how the obstetric gestational age is determined. Adding another two weeks, you get the time of conception. This is an imprecise method: not all babies are born at term. If you remember the estimated date of birth, which was announced by the gynecologist, then by doing calculations with it, you can guarantee greater accuracy. The advantage of the method is that it helps to establish paternity without genetic tests.

Basal Temperature Measurement Calendar

When ovulation occurs, hormonal changes occur in the body, causing an increase in basal body temperature.. This is a natural process. Daily measure the temperature in the anus and put it in the table. To minimize the error, follow the rules:

take measurements in the morning at the same time;
without getting up, measure the temperature motionlessly for 5 minutes;
take measurements with one thermometer, since the error matters.

It is pointless to measure the temperature in other places, it rises only in the anus. If a woman is overheated or sick, the thermometer may show high numbers, but this will not be associated with ovulation. The basal temperature calendar with an irregular cycle allows you not to miss the moment of the release of the egg, but requires painstaking work.

Calculate conception days online

Women watch for delays in menstruation. Previously, they were forced to cross out the "red" dates manually, now there are services that record observations of the menstrual cycle online. The program will help calculate the period favorable for conception and suggest safe days. You should not use a female calendar as a method of contraception. Record your basal temperature, mood, well-being, discharge, sex in apps. This information will help when planning pregnancy and when visiting a gynecologist. Convenient Apps:

Feminap (Android);
Monthly: women's calendar (iOS);
4WomenOnly (Windows);
Flo - women's period and pregnancy calendar (Android, iOS).

Folliculometry

A reliable method for monitoring the stages of egg maturation is folliculometry. Painless ultrasound diagnostics is performed externally or vaginally. The timing of the examination is selected by the gynecologist: 7-12 days from the onset of menstruation with a regular cycle and 3-5 days with an irregular one. Studies are carried out daily or every other day before ovulation. If the release of the egg did not occur, ultrasound is carried out until the next menstruation.

Folliculometry is an accurate method that requires a visit to the clinic and financial costs, therefore it is recommended for women with:

infertility;
hormonal disorders;
preparation for artificial insemination;
stimulation of ovulation;
carrying out IVF.

Special Tests

Pharmacies sell strips similar to pregnancy tests to determine ovulation. Diagnosis is based on the content of luteinizing hormone in the urine, indicating that the egg is ready for fertilization. 17 days before menstruation, you need to conduct such a study 5 days in the morning and in the evening. In addition to tests that analyze urine, there is a perfect reusable system that examines saliva.

device works like a microscope. You need to drip saliva on the glass and wait for it to dry. The ovulation microscope analyzes the remaining trace. Progesterone and estrogen affect the composition of saliva. The device has many advantages. To diagnose, you do not need to look for a toilet. Thanks to accuracy and simplicity, it is possible to calculate not only favorable days for conception, but also safe days.

With these tests, you can plan the sex of the child. If intercourse occurs on the day of ovulation, it is likely to be a boy, since Y-sperm is faster than X. If sex was a few days before, then a girl will most likely be born. This result is explained by the fact that more viable X-sperms are more likely to wait for the release of the egg.

How to find out the day of conception of a child already pregnant

The doctor can determine the date of conception as accurately as possible by the level of the hCG hormone and the results of ultrasound. In the first trimester of pregnancy, the indicator for establishing gestational age is the size of the uterus, which depends on the intrauterine size of the fetus. This is necessary to clarify the EDD (preliminary date of birth). At a later date, the estimated day of conception can be estimated by the pace of development of the child, the movements of the baby.

With the help of the conception calendar, a woman can control her menstrual cycle, calculate ovulation and the days when the probability of becoming pregnant is higher.

conception calendar- this is a form in which you just need to enter the number of the first day of the last menstruation, and a special program will automatically calculate the possible days of conception, highlighting them in different colors. Using this calendar is very simple and effective.

To understand the effectiveness and main provisions of this program, consider the following factors that were taken as the basis for its construction:

women have one day of ovulation when the egg is mature and ready to be fertilized. This day is in the middle of the menstrual cycle. In the conception calendar, this day and a couple of days before and after it are highlighted in red and orange.
days on which it is almost impossible to get pregnant (if you have a regular menstrual cycle) are highlighted in white on the calendar. These days fall at the time of menstruation and at the end of the cycle.

To check the effectiveness of this program, observe the state of your body during the period of ovulation:

1. there is an increase in the amount of vaginal discharge;
2. increases sexual desire;
3. the temperature in the rectum rises;
4. a positive result is displayed in the ovulation test;
5. the appearance of short aching pains in the ovaries and uterus;
6. Ultrasound shows signs of the release of the egg from the ovary.

To calculate the days of possible conception and the date of ovulation right now, you need to enter a specific date for the start of your period, and within a few seconds you will receive the necessary information.
But keep in mind that you can not completely rely on these calculations. This happens because the processes in our body can be affected by a change of place of residence, stress and much more.
In addition, not every cycle occurs ovulation. With this in mind, every woman has cycles that are "sterile".

Your first day of your period.

The birth of a baby is a great happiness for those who are waiting for it. Which days are favorable for conception for some women is an urgent question, while others are interested in how to prevent an unplanned pregnancy. Simple, time-tested methods for determining the period for conception will help in both the first and second cases.

Probability of getting pregnant

Fertilization of the egg occurs if there was unprotected intercourse, and ovulation occurred in the current month. When planning a pregnancy, a woman should initially visit a gynecologist, undergo an examination and make sure that there are no health problems. Before taking, you need to calculate your cycle and remember the date of the beginning of the last menstruation. A 28-day cycle is considered ideal. High probability of pregnancy is especially high on day 14.

What days of the cycle can you get pregnant

Contrary to methods of protection and condoms, any days of the cycle for conception are favorable. The fertile period begins five days before ovulation - the maturation of the egg. This means that hormonal changes have begun in the cervical mucus. It creates favorable conditions for spermatozoa, and the expansion of the uterine os facilitates the penetration of the spermatozoon into the egg.

Chances of getting pregnant during your period

What days can you get pregnant? All days. For example, with a hormonal failure or prolonged nervous tension, the egg matures until the middle of the menstrual cycle or does not mature at all. So if you are interested in what is the probability of getting pregnant during menstruation, then it is very high, especially in recent days. Abundant bleeding in the first menstrual days creates an unfavorable atmosphere for spermatozoa, but with a long protracted menstruation, the risk of conceiving a baby increases.

Chances of getting pregnant after period

Most girls believe that it is impossible to get pregnant after menstruation. Two days after the regulation are characterized by a low chance of pregnancy. However, it is worth considering that it is not zero. What is the chance of getting pregnant immediately after menstruation? In theory, the female body works by the clock, but in practice there is no way to accurately calculate how many days after menstruation you can get pregnant.

Is it possible to get pregnant a few days before menstruation

When menstruation comes, this does not mean that a woman cannot become pregnant. Women with a stable menstrual cycle are as likely to become a mother as those with irregular cycles. The chances of conceiving a child are different on certain days of the cycle. The best time to get pregnant is a week before your period . The days of the cycle can be divided into 4 phases:

With follicular, the maturation of the follicle begins.
Ovulatory accompanies the release of the egg.
During the luteal phase, a change in the hormonal background for conception occurs.
End: desquamation - the egg is released with the endometrium.

Calculate ovulation calculate

Gynecologists call a good time for getting pregnant ovulation - the procession of an egg into the fallopian tube as a result of a rupture of a mature follicle. Some women can even feel it. You can feel that you have ovulated by signs:

the breast is enlarged;
sensations of sipping, heaviness in the lower abdomen;
basal temperature rises;
increased desire to have sex;
the amount of clear discharge increases.

At this moment, the body itself tells the woman what her main purpose is. How to correctly determine ovulation for conception if you do not have the above symptoms? For this purpose, online calculators are suitable, where you need to enter the start date of the last menstruation and the duration of the entire cycle. You can calculate the days using a regular calendar: ovulation cannot occur earlier than 14 days before menstruation, but it all depends on the length of the cycle.

Safe days from pregnancy

There is a myth that there are safe days after menstruation on which you will not be able to get pregnant. But with unprotected intercourse, there is always a chance of fertilization of the egg. So what day after menstruation can you get pregnant? Gynecologists say that in any: without contraception, you will not be 100% protected from the likelihood of a child. The chance of conception is lowest two days before and after bleeding. Find out ways, if it is undesirable.

Dangerous days for pregnancy

Pregnancy is always possible when a woman is healthy and disposed to childbearing. There are dangerous days that those who have not yet thought about procreation are afraid of. You can determine the chances of getting pregnant using an online menstruation counter or by yourself. Calculating which days are favorable for conception is simple: you need to take your menstrual calendar for the last six months and calculate the average cycle (from the first days of the regulation to the next):

28 days - ovulation occurs on the 14th day.
33 days, a good moment falls on the 17th day.

The table of ovulation days implies the entry of basal temperature data. It's an easy way to know when your body is changing and calculate the days to conceive. . Ovulation occurs in the second phase of the cycle and is characterized by an increase in basal body temperature. The measurement procedure is carried out in the morning, using a conventional thermometer, which is inserted into the vagina immediately after waking up. The ovulation schedule includes two phases of the cycle:

vertical line - basal temperature value from 35.7 to 37.2;
horizontal line - days of the menstrual cycle (normal range from 28 to 32).

The development of pregnancy begins with the fertilization of the egg by the sperm. The day of their merger is considered the date of conception of the unborn child. There are various methods for calculating the date of possible fertilization, all of which are based on determining the day of ovulation - the moment the egg matures.

Exact day of conception: how to find out

Favorable days for conceiving a child

It is believed that a woman can only become pregnant when she is ovulating. At this time, the fertilized egg is released from the ovary into the uterine cavity. She lives no more than 48 hours, so the couple may not have so much time to conceive a child during one menstrual cycle.

Male sperm, once in the vagina, at best, can live for about seven days. Therefore, conception is possible only a few days before ovulation, as well as on the day the egg is released into the uterine cavity.

How to find out the exact date of conception

To find out when conception occurred, you need to find out the date of ovulation and compare it with the day when unprotected sexual contact occurred.

To calculate the exact day of fertilization, you can use a special calculator by finding it on websites about pregnancy and childbirth, but this is easy to do on your own.

If a woman has been monitoring her ovulation, determining the exact date of conception is very simple. This will be the day on which the sexual intercourse closest to this date took place.

Calculating the date of ovulation is possible by measuring basal body temperature, using ultrasound, a blood test for hormone levels, and using diagnostic rapid tests to establish ovulation.

On the basal temperature chart, the day of ovulation is the moment the line of the measured indicator moves to a higher level (temperature rise by 0.3–0.5 degrees)

If a woman did not follow the onset of ovulation, it will be somewhat more difficult to establish the exact date of conception. An egg ready for fertilization is released from the ovary around the middle of the menstrual cycle. The duration of the period between the onset of menstruation in different women varies and can range from 24 to 40 days, so both early and late ovulation is possible. In most cases, it happens 14 days before the date of the expected menstruation.

When going to the antenatal clinic, the doctor informs the woman about the gestational age. You can find it out (if the date of the beginning of the last menstruation and the moment of ovulation is unknown) according to the results of a gynecological examination or ultrasound data. According to the established date, it is possible to calculate the date of the expected birth. According to these data, using a special formula, you can find out on which day the conception occurred. From the date of birth, you need to count a week and add three months and two weeks to the resulting number. On the day received, fertilization most likely occurred. However, please note that this result is approximate.

When a woman plans to get pregnant and give birth to a baby, she dreams of seeing the cherished “two stripes” on the test, but how to determine the day favorable for conceiving a child?

It’s worth saying right away that you won’t be able to set a 100% exact date for the conception of a baby before the day, but you can determine the day of ovulation in order to plan a pregnancy, and then wait for signs of pregnancy or test results. How to find out the exact day of ovulation in order to plan a pregnancy with a high probability? Let's figure out together how to determine the day of conception of a child!

When you want to find out what are the most favorable and most likely days for conceiving a child, you need to calculate the day of ovulation as accurately as possible. Today there are a large number of ways to establish this point:

The easiest and most common way to "calculate" ovulation is by basal temperature. Ovulation will occur after a temperature drop, which occurs 24 hours before the release of the egg from the follicle. Here we can note a decrease in basal temperature by 0.1-0.2 degrees. When ovulation occurs, the basal temperature rises by 0.2-0.5 degrees and will exceed 37 degrees.
For ovulatory syndrome. There are women who, during the period of ovulation, have pulling pains in the area of the active ovary, which are quite sensitive and noticeable. Therefore, some ladies experience short-term malaise and discomfort during the period of ovulation.
By the nature of the mucus that is secreted from the vagina. If in the first phase of the cycle, the vaginal mucus is thick and sticky, then before the egg begins to ovulate, it becomes transparent and viscous and resembles the white of a chicken egg. In some cases, the release of an egg ready for fertilization from the follicle is associated with damage to blood vessels, so a woman notices small bloody impurities in the vaginal discharge in the middle of the cycle.
Using the folliculometry method. In this case, ultrasound is used, through which the monitoring of how the egg matures is carried out. This method allows you to accurately calculate the day when the egg ovulates.
Using a special ovulation test. Many modern women are aware of what a pregnancy test is and have used it. So, the ovulation test works on a similar principle, but the reaction occurs to an increase in the concentration of LH - luteinizing hormone, the so-called fertility hormone.

A trip to the gynecologist will also help to resolve this issue, since the doctor, when examined on an armchair, can quite accurately determine the approaching ovulation. If you want to accurately calculate this day, then you can use several of the above methods at the same time.

To conceive a child, nature "gives" a few days

Even if you know exactly when the last sexual intercourse took place, after which the long-awaited pregnancy occurred, then it is impossible to say that this particular day is the date when the child was conceived. As you know, sperm can take several days to reach the egg, and one day may not be enough for fertilization. In addition, a sperm cell that has arrived at the “meeting field” may be left out of work, since the egg has not yet left the follicle.

It happens that spermatozoa "wait for ovulation, being nearby." Experts say that the conception of a baby, from a theoretical point of view, can come from sexual intercourse that occurred both a few days before ovulation, and a couple of days after its onset.

Having discovered signs or learned the results of a pregnancy test, a woman is in seventh heaven with happiness, because now an unforgettable time of bearing a child begins, filled with a special meaning for the speedy birth of a baby. The importance of pregnancy in a woman's life is difficult to overestimate, but it often happens that the expectant mother did not follow the moment of conception, and now she wants to know when this wonderful event happened, keep in mind, calculate and find out the day of the conception that took place up to the day is not so and easy.

It is almost impossible to calculate the exact date when the child was conceived if the pregnancy has already been confirmed. Of course, if you have an irregular sex life, and you remember exactly the dates of sexual contact, then it is possible to determine this moment with an accuracy of day to day. But 100 percent probability will not be due to the fact that conception is possible only during the period when the egg was ovulated. Few women in the same period of the cycle spend time calculating ovulation for several months in order to make an approximate forecast of which days this will happen.

If a woman kept an ovulation calendar, that is, she regularly tracked the moments when an egg was released from the ovary into the fallopian tube as a result of a rupture of a mature follicle, then she can know the dates when ovulation occurred quite accurately and, as a result, find out the day of conception. It is necessary to subtract two weeks from the date on which the first day of menstruation is expected, that is, 14 days. It is generally accepted that ovulation occurs, if we take the average value, 14 days before the start of the next menstruation. If your cycle is standard and equals 28 days, then ovulation, in fact, occurs on the 14th day of the cycle. If the cycle is longer and is 31 days, then on day 17, and when 25 days, then on day 11, but all the same, such calculations are considered conditional. The secret is that the process of ovulation is associated with many factors that cannot be predicted in any way when calculating the approximate date of conception.

To determine a more accurate date of conception, you can go to an ultrasound examination (ultrasound) of the fetus, and there, after the examination, a specialist doctor will be able to give you an approximate gestational age, although this date cannot be considered 100% accurate either.
