How to know the date of conception of a child: a description of different methods

After the woman learns that she is pregnant, she certainly wants to know the date of the expected delivery. And this means that she, first of all, should know the date of ovulation. In this article, we'll talk about how to find out the date of conception of a child.

Today there are a huge number of calculators with which you can find out the date of conception. All of them work on the same principle. By the first day of the last menstruation, you need to add two weeks, as most often ovulation and fertilization occurs in the middle of the menstrual cycle. This is provided that the menstrual cycle lasts 28 days.

Given the female identity, in order to find out when the baby was conceived, it is necessary to divide in half not in 28 days, as the rule says, but the number of days that enter the menstrual cycle of a particular woman. For example, if menstruation lasts 24 days, then most likely, the date of ovulation will be 10-13 of the month.

Many women think that the day of conception of a future child is the day when sexual intercourse was performed. However, this opinion is erroneous, because the male seed can meet the ovum even on the 5th day after sexual intercourse. It all depends on how mature the egg is and the active seed. By the way, the egg is attacked by a huge number of spermatozoa. Their number can be even five hundred million spermatozoa.

The definition of the day of conception is very important, since without knowing this date, as already mentioned above, it is impossible to calculate the birthday of the future child.

How to determine the date of ovulation?

• basal temperature: ovulation occurs after a temperature-induced occlusion, observed the day before the release of the oocyte from the follicle( there is a decrease in BT by 0.1-0.2 degrees).Then, after the onset of ovulation, the indices rise by 0.2-0.5 degrees and exceed 37 ° C;
• by the nature of the vaginal mucus: before ovulation, the sticky and thick in the first phase of the vaginal discharge become viscous and transparent, like egg white. The exit of a mature egg can be accompanied by damage to the blood vessels, that the woman observes insignificant blood impurities in the vaginal secretions in the middle of the cycle;
• for ovulatory syndrome: some women with hypersensitivity can feel the pulling pains from the active ovary and even complain of a prolonged indisposition during this period;
• using an ovulation test: works on the same principle as a pregnancy test, but unlike the latter, it reacts to an increase in the concentration of the so-called hormone of fertility( LH-luteinizing hormone);
• by the method of folliculometry: the process of maturation of the ovum is followed by ultrasound observation, which allows to determine the day of ovulation sufficiently accurately.

To all other things, the approach of ovulation can be determined quite accurately by an experienced gynecologist while examining a woman on the chair. The most reliable result can be obtained by combining several methods at once.
