Most women prefer to plan their pregnancy in advance because the body needs to prepare. This is important both for the expectant mother herself and for the child. The question of how to calculate the date when it is possible to become pregnant worries every woman who is going to have a child.
The menstrual cycle is the period when the female body prepares for pregnancy. The duration of this cycle for most women is twenty-eight days. At different stages of the menstrual cycle, the release of sex hormones is not the same. Under the influence of one of the hormones produced by the pituitary gland, at the beginning of the menstrual cycle, a follicle matures in a woman's ovary. As it grows, it gradually moves to the surface of the ovary. This advancement occurs under the influence of another hormone of the anterior pituitary gland - lutein.
The egg cell contained in the follicle also gradually increases, and by the time the follicle ripens, it is also mature. It takes a certain time for the follicle to fully mature. With a menstrual cycle of twenty-eight days, this period is fourteen days. So, having reached the surface of the ovary after fourteen days, the follicle bursts, and a mature egg cell, ready for fertilization, comes out of it.
Thus, with a twenty-eight-day menstrual cycle, the most favorable time for conception is the fourteenth and fifteenth days from the first day of the cycle. The beginning of each next cycle is the end of menstruation.
Each woman can independently determine the time of ovulation. To do this, you need to measure the basal temperature. As a result of the changes that occur in the internal genital organs under the influence of certain hormones, the basal temperature indicators also change. It allows you to determine the timing of ovulation and the ability of the ovaries to produce progesterone.
Basal temperature should be measured in the morning at the same time, without getting out of bed, since it is necessary to exclude any activity. You need to measure the basal temperature in the same way - either vaginally or rectally, and enter the readings into a special schedule. In the first half of the cycle, when ovulation has not yet occurred, the basal temperature, on average, is 36.5 - 36.9 degrees. With the onset of ovulation, it rises and becomes above 37. The greatest probability of conception exists two days before the temperature rises and on the day when ovulation occurs.
However, it is worth noting that if sexual intercourse took place on the indicated days, then this is not a guarantee that pregnancy will occur. This often happens after several months of unsuccessful attempts to have a child, even if both parents-to-be are perfectly healthy. Don't worry, because overwork and worry is a common cause of failure.
