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

Reading time: 5 minutes

Doctors strongly recommend that women mark the beginning of each period on a calendar so that, based on this data, they can calculate the date of ovulation and calculate the period of conception of the child. Not every sexual intercourse leads to the fertilization of an egg. For a successful pregnancy to occur, a number of processes must occur in a woman’s body, which will be discussed below.

What is the period of conception

From the first day of the cycle, the body begins to prepare for pregnancy. Follicles mature inside the ovaries. One develops faster. At the moment the follicle ruptures, the mature egg penetrates the fallopian tube. This process is called ovulation. An unfertilized egg lives for a day. If fertilization does not occur, she dies and comes out with menstruation. Sperm are more viable. Some die on the way from the vagina, but those that penetrate the fallopian tubes wait for an egg for 3-4 days. The period of conception is a period in the middle of the cycle lasting 4 days: three before ovulation and one after.

What does knowing the date give?

To calculate timing of conceiving a child, you need to calculate the date of ovulation. Sexual intercourse should occur no earlier than 4 days before, and no later than 24 hours after it. This 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 you can calculate when this happened most likely.

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 fickle. Sexual contact can cause premature release of the egg, and stress and fatigue can cause late ovulation. A woman can determine the onset of the ovulatory period by sensations. Indirect signs of ovulation:

pain in the lower abdomen;
mucous discharge from the vagina;
change of mood;
increased sexual desire.

Calculate the date of conception based on the last menstruation

Doctors consider the date of conception to be the first day of the last menstruation. The obstetric period exceeds the embryonic period 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 their last menstruation. The calendar method for determining ovulation is suitable for regular cycles. For several months, record information about the beginning of menstruation in your calendar. Divide the average cycle length in half. If you add the resulting number to the first day of your last period, 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. Add another two weeks to get your fertilization time. This is an imprecise method: not all babies are born at term. If you remember the estimated date of birth announced by the gynecologist, then by making calculations with it, you can guarantee greater accuracy. The advantage of this method is that it helps establish paternity without genetic tests.

Basal temperature measurement calendar

During ovulation, hormonal changes occur in the body, causing an increase in basal temperature. This is a natural process. Measure the temperature in the anus daily and record it in a table. To minimize the error, follow the rules:

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

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

Calculate days of conception online

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

Feminap (Android);
Menstruation: Women's Calendar (iOS);
4WomenOnly (Windows);
Flo – women's calendar of periods and pregnancy (Android, iOS).

Folliculometry

A reliable method of monitoring the stages of egg maturation is folliculometry. Painless ultrasound diagnostics are performed externally or vaginally. The gynecologist selects the timing of the examination: 7-12 days from the start of menstruation with a regular cycle and 3-5 days with an irregular one. Research is carried out daily or every other day before ovulation. If the egg is not released, an ultrasound is performed before 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 the readiness of the egg for fertilization. 17 days before menstruation, you need to conduct such a study 5 days in the morning and evening. In addition to tests that analyze urine, there is a perfect a reusable system that examines saliva.

Device works on the principle of a microscope. You need to drop saliva onto the glass and wait for it to dry. An ovulation microscope analyzes the remaining trace. Progesterone and estrogen affect the composition of saliva. The device has many advantages. To carry out a diagnosis, you do not need to look for a toilet. Thanks to accuracy and simplicity, you can calculate not only favorable days for conception, but also safe days.

These tests can be used to predict the sex of the baby. If sexual intercourse takes place on the day of ovulation, it will probably be a boy, since Y sperm are faster than X. If sex took place a few days before, then a girl will most likely be born. This result is explained by the fact that more viable X sperm have a better chance of waiting for the egg to be released.

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

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

With the help of a conception calendar, a woman can control her menstrual cycle, calculate ovulation and 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 your 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 for fertilization. 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 occur during menstruation and at the end of the cycle.

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

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

To calculate the days of possible conception and the date of ovulation right now, you need to enter the specific date of the start of menstruation, and within a few seconds you will receive the necessary information.
But please note that you cannot rely entirely 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, ovulation does not occur in every cycle. With this in mind, every woman has cycles that are “infertile.”

Color meaning

The most likely day of ovulation, the best day to conceive.
The probability of conception is 90%.
The probability of conception is 80%.
Your first day of your period.

The birth of a baby is a great happiness for those who are expecting it. Which days are favorable for conception for some women is a pressing 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.

Chance of getting pregnant

Fertilization of the egg occurs if there was unprotected sexual 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 it, you need to count your cycle and remember the date of the last menstruation. A 28-day cycle is considered ideal. High probability of pregnancy is especially high on the 14th day.

On what days of the cycle can you get pregnant?

Despite birth control methods and condoms, any day of the cycle is favorable for conception. 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 sperm, and the expansion of the uterine os facilitates the penetration of sperm into the egg.

Chances of getting pregnant during your period

On what days can you get pregnant? On all days. For example, in case of hormonal imbalance or prolonged nervous tension, the egg matures until the middle of the menstrual cycle or does not mature at all. So if you are wondering what the probability of getting pregnant during your period is, then it is very high, especially in the last days. Heavy bleeding in the first menstrual days creates an unfavorable atmosphere for sperm, but with long, protracted menstruation, the risk of conceiving a baby increases.

Chances of getting pregnant after menstruation

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 probability of getting pregnant immediately after your period? 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 your period?

When menstruation occurs, this does not mean that a woman cannot become pregnant. Women with a stable menstrual cycle are just as likely to become mothers as those with an irregular cycle. 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 an egg.
During the luteal phase, a change in hormonal levels occurs for conception.
End: desquamation - the egg is released with the endometrium.

Ovulation calculation calculate

Gynecologists call a good time to become pregnant ovulation - the passage of an egg into the fallopian tube as a result of the rupture of a mature follicle. Some women can even feel it. You can feel that you are ovulating by the following signs:

breast enlarges;
sensations of stretching, heaviness in the lower abdomen;
basal temperature increases;
increased desire to have sex;
the amount of transparent 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 signs described above? Online calculators are suitable for this purpose, 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 during which you will not be able to get pregnant. But with unprotected sexual intercourse, there is always a chance of fertilization of the egg. So what day after your period can you get pregnant? Gynecologists say that in any case: without contraception, you will not be 100% protected from the likelihood of having a child. The likelihood of conception is lowest two days before and after bleeding. Find out ways if it is unwanted.

Dangerous days for pregnancy

Pregnancy is always possible when a woman is healthy and ready to bear children. There are dangerous days that those who have not yet thought about procreation fear. You can determine your chances of getting pregnant using an online menstruation counter or doing it yourself. It’s easy to calculate which days are favorable for conception: you need to take your menstrual calendar for the last six months and calculate the average cycle (from the first days of regulation to the next):

28 days – ovulation occurs on the 14th day.
33 days, the lucky moment falls on the 17th day.

Ovulation schedule

The ovulation days table involves entering basal temperature data. This is an easy way to find out when changes occur in the body and calculate the days for conception . Ovulation occurs in the second phase of the cycle and is characterized by an increase in basal temperature. The measurement procedure is carried out in the morning, using a regular 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 limits from 28 to 32).

The development of pregnancy begins with the fertilization of an egg by a 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 during ovulation. At this time, the fertilized egg leaves the ovary into the uterine cavity. She lives no more than 48 hours, so a couple may not have much time to conceive a child during one menstrual cycle.

Male sperm, once in the vagina, can live for about seven days at best. 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 intercourse occurred.

To calculate the exact day of fertilization, you can use a special calculator, finding it on websites about pregnancy and childbirth, but it’s easy to do it yourself.

If a woman monitored her ovulation, it is very easy to determine the exact date of conception. This will be the day on which the closest sexual intercourse occurred to this date.

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

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

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

When going to the antenatal clinic, the doctor informs the woman about the duration of her pregnancy. You can find out (if the start date of the last menstruation and the moment of ovulation are unknown) by the results of a gynecological examination or ultrasound data. Based on the established period, it is possible to calculate the date of expected birth. Using this data, using a special formula, you can find out on what day conception occurred. You need to count a week from the date of birth and add three months and two weeks to the resulting number. On the resulting day, 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 coveted “two lines” 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 establish the 100% exact date of conception of the 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 will need to calculate the day of ovulation as accurately as possible. Today there are a large number of ways to establish this point:

The simplest and most common way to “calculate” ovulation is by basal temperature. Ovulation will occur after the temperature drop, which is observed 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 exceeds 37 degrees.
According to ovulatory syndrome. There are women who, during the period of ovulation, experience nagging pain in the area of the active ovary, which is quite sensitive and noticeable. Therefore, some women experience short-term malaise and discomfort during ovulation.
According to the nature of the mucus that is released 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 the 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 to monitor how the egg matures. 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 visit to a gynecologist will also help resolve this issue, since the doctor, during an examination on the chair, can quite accurately determine the approaching ovulation. If you want to accurately calculate this day, you can use several of the above methods at the same time.

To conceive a child, nature “gives” several days

Even if you know exactly when the last sexual intercourse occurred, after which the long-awaited pregnancy occurred, 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, the sperm that arrives at the “meeting field” may be left out of work, since the egg has not yet left the follicle.

It happens that sperm are "waiting for ovulation by being nearby." Experts say that, from a theoretical point of view, conception of a baby can occur from sexual intercourse that occurs both a few days before ovulation and a couple of days after it occurs.

Having discovered the signs or learned the results of a pregnancy test, a woman is in seventh heaven, because now the unforgettable time of bearing a child begins, filled with the special meaning of the speedy birth of the baby. The importance of pregnancy in a woman’s life is difficult to overestimate, but it often happens that the expectant mother did not keep track of the moment of conception, and now wants to find out when this wonderful event happened, keep in mind, calculating and finding out the day of conception with an accuracy of 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 intercourse, then it is possible to determine this moment with day-to-day accuracy. But there will not be a 100 percent probability due to the fact that conception is possible only during the period when the egg has ovulated. Few women in the same period of the cycle spend time calculating ovulation over several months in order to make a rough prediction on which days it 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 the rupture of a mature follicle, then she can know the dates when ovulation occurred quite accurately and ultimately 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 to occur, 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 you have a standard cycle of 28 days, then ovulation actually occurs on the 14th day of the cycle. If the cycle is longer and is 31 days, then on the 17th day, and when it is 25 days, then on the 11th day, but all the same, such calculations are considered conditional. The secret is that the ovulation process is associated with many factors that cannot be predicted when calculating the approximate date of conception.

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