Pregnancy, future motherhood and paternity are among the most important events in life. After receiving the news about the imminent replenishment, parents are always tormented by the question: who will be born? Girl or boy? Since ancient times, there have been many methods and signs for sex determination, but none of them guarantees a 100% result.

How to conceive a boy or girl?

Science has proven that the sex of the baby is programmed at the moment of conception. The fact is that both men and women have two chromosomes. In men there is a Y chromosome and an X chromosome, in women there are 2 X chromosomes. It is the male chromosome, whether X or Y produces fertilization, that determines the sex of the child. Although a man's body produces approximately the same number of X and Y chromosomes, there is still a chance of conceiving a child of the desired sex.

Any organism healthy woman designed so that conception can only occur on certain days of the month. As you know, a woman’s menstrual cycle has a strictly individual period, it ranges from 25 to 35 days. Around the middle of the cycle, ovulation occurs, that is, the release of an egg from the ovary. Pregnancy will occur if during the period of ovulation there is a meeting with a male sperm cell.

Gender of the child by date of conception, day of ovulation and conception

A woman's menstrual cycle is 28 days, with the start date of her last menstrual period being May 31st. Thus, her cycle in the current month is from May 31 to June 27. The estimated date of ovulation in this case is June 13. The chances of getting pregnant are high if you make love between 4 days before ovulation and 2 days after, that is, from June 9 to June 15.

Science has already proven that sperm with a Y chromosome (the so-called male) move faster than sperm with an X chromosome (female). Although male cells reach their target (eggs) faster, they also die faster. Female cells are slower in this regard, but tenacious.

How to conceive a boy? To become pregnant with a boy, sexual intercourse must occur exactly on the day of ovulation or within a few hours after it.

How to conceive a girl? To get pregnant with a girl, it is best to have intercourse the day before ovulation.

Example calculation for the same woman:

When ovulating on June 13, to increase the chances of giving birth to a boy, sex should be immediately on the day of ovulation and a little later, that is, on June 13 and 14. In order to get pregnant with a girl, sex must take place on June 11 or 12.

It is important to understand that although this calculation has been scientifically proven, it is impossible to guarantee an exact result, because any female body unique.

An ovulation calendar can be very useful for those women who are planning a pregnancy in the near future. There are many ways to determine the only day in the cycle when fertilization of an egg can occur, but using the program is still easier. We will tell you how the ovulation and conception calendar works, how to use it and what other methods exist to identify the “right” day.

The program is configured in such a way that it calculates the exact middle of the menstrual cycle depending on its duration, this is the day the egg is released from the ovary. A few more days before and after this are considered possible for fertilization, the rest are safe. The ovulation calendar allows you to calculate all these points and visually see the result in the form of dates marked in different colors.

In addition, you can use non-automatic methods, such as: an increase in basal temperature, some subjective sensations, special tests and even ultrasound.

The most accurate of the above is ultrasound. But to get a reliable result, you will have to do it for several days in a row, and this is not a cheap pleasure. It’s much more profitable to calculate the ovulation calendar online. However, in the case of true infertility, ultrasound monitoring cannot be avoided.

To learn how to determine the phases of your menstrual cycle by measuring basal temperature, you will also need to learn how to draw up the correct schedule and carry out measurements according to all the rules, otherwise annoying mistakes may occur. If you intend to create a calendar of ovulation and conception on your own, then you must get used to not getting up at night to go to the toilet (the temperature is measured after at least 6 hours of being in a calm, lying position), buy a good thermometer (a simple mercury thermometer will do), and know what temperature values ​​mean what. Yes, during ovulation rectal temperature slightly exceeds 37 degrees, and before it ranges from 36.6 to 36.9. A basal temperature chart may also be needed for a doctor, so that he can at least superficially judge the condition of your body. reproductive system, more precisely, your hormonal background.

In addition, a day favorable for conception can be easily determined by girls who carefully monitor their health. For example, in the middle of the cycle, the amount of colorless or slightly whitish vaginal discharge may increase, or the stomach may not hurt much. If you try to calculate the ovulation calendar online, you can make sure that it is on those days that pregnancy is likely to occur.

For less sensitive girls, special ovulation tests can be purchased. Good luck!

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 the last menstruation, and a special program will automatically calculate possible days conception, highlighting them different colors. Using this calendar is very simple and effective.

To understand the effectiveness and main provisions of this program, consider the following factors, which 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. In the ovulation test it is displayed positive result;
5. 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.”

Ovulation is a complex aspect of the female body, especially compared to its simplicity male hormones and reproductive cycle. Not all women have a "standard" 28-day cycle. Often the length of the cycle is individual, or it generally changes from cycle to cycle. For example, changes may be caused by illness or stress. For these reasons, it is useful to use an ovulation calculator to calculate the phases of your cycle.

How to calculate ovulation

For calculations, 2 parameters are used: the start date of the last cycle and the average cycle length. As mentioned above, a "normal" cycle is 28 days (although deviations and slight fluctuations are normal). The first day of your menstrual cycle is the first day of bleeding or the start of your period. Ovulation usually occurs between days 11 and 21 of the cycle. The calculator will calculate this date more accurately based on middle length your cycle. In this case, the accuracy of calculating ovulation depends on the regularity of your cycle.

How accurate is an ovulation calculator?

If you have any doubts or suspicions about the normality or regularity of your cycle, the ovulation calculator may not provide accurate results. To use the calculator, you first need to track your cycles, preferably within long period- 8 - 12 months. In addition, the results will not be reliable if hormonal contraceptives, illness, stress. If you want to calculate ovulation with greater accuracy, we recommend using the calculator in combination with other methods for determining ovulation.

It may be hard to believe, but there is only one day in a month on which a woman can become pregnant. IN exceptional cases such a day occurs twice during one menstrual cycle, but in the vast majority of “hour X” lasts only a day, and they are called ovulation.

On the day of ovulation, which we will now teach you how to calculate, a mature egg is released from its follicle. Within 24 hours she will wait for fertilization, and if she is unclaimed, she will die. Only 24 hours a month, and even then it’s best case scenario. It happens that ovulation does not occur, and even with regular menstrual cycle on average in women who do not experience any gynecological problems, 10 ovulations occur per year, that is, not monthly.

Girls who decide to calculate the day of ovulation for the purpose of contraception should be immediately warned: pregnancy will be very likely if you had unprotected intercourse a few days before ovulation, since sperm, unlike eggs, are more tenacious and retain the ability to fertilize for several days .

But if you are trying to calculate, then you should definitely know how to calculate the day of ovulation.

How to calculate the days of ovulation?

There is a very simple formula that allows you to calculate the day of ovulation at home without additional equipment. By the way, there are ready-made ones that simplify the task, but there is nothing complicated in the calculations anyway.

It has been found that ovulation in any woman with any length of the menstrual cycle occurs exactly 14 days before the start of the next menstruation. The duration of the first phase may vary, but the period after ovulation is constant. If your menstruation occurs regularly “number after number”, then calculating the day of ovulation will be easier:

Ovulation day = next menstruation date - 14 days.

A classic example: with a regular 28-day menstrual cycle, ovulation occurs on the 14th day of the cycle. If your period started on the 3rd this month, then with a 28-day cycle, expect ovulation on the 17th, 14 days before the start of your next period. If your cycle is longer or shorter, then add the length of the cycle to the first day of your last period (for example, 26 or 30). You will receive the expected date of your next period, from which you need to subtract 14 days, resulting in the date of ovulation in this cycle.

Actually, the calendar method of contraception is built on this principle.

Calculating ovulation is very simple, but it has one rather significant BUT: the method is applicable only for women with a regular cycle, and you should take into account the schedule for at least the last 4-6 months.

If you are trying to get pregnant and for this purpose are looking for how to calculate the day of ovulation, then the following advice will be useful for you. With a regular menstrual cycle lasting 26-30 days, the chances of conceiving a child increase significantly if you have intercourse every other day from the 10th to the 18th days of the cycle.

Can an ovulation calculator be wrong?

For couples, calculating ovulation is extremely important. However, this method cannot be considered highly accurate. The fact is that ovulation is very labile. Under the influence of a number of factors, even with a regular menstrual cycle, it can shift. This, in particular, can be caused by stress, overwork, colds, and hormonal imbalances. Moreover, in rare cases, ovulation can occur twice in one cycle, which should be especially remembered when using contraception. Well, it is not at all excluded that ovulation will not occur at all in this cycle. Therefore, experts recommend using methods for determining ovulation in combination: focusing on your own feelings, keeping a chart basal temperatures, take advantage of . And the most accurate would be to carry out ultrasound examination, which can determine ovulation as reliably as possible.
