A woman planning a pregnancy should know how to determine the date of conception of a child so as not to miss ovulation, which lasts only one day. Also, it is equally important to have an idea how to find out the date of conception of a child, since it is on this basis that the date of birth is calculated.
How to determine the exact date of conception of a child?
Date of birth is determined by the date of conception of the child is very simple. The average duration of the menstrual cycle is 28-35 days. Ovulation occurs in the middle of the cycle. When a woman knows how to calculate the day of conception, then the date of delivery will not be a problem. If a woman does not know exactly when the ovulation period was, you should calculate the middle of the cycle and add 280 days to it. True, the date will be approximate, since in this case it is impossible to know the exact date of conception of the child. Spermatozoa remain viable for several days, therefore, fertilization could occur and not on the day of ovulation, but a couple of days later.
How to calculate the day of conception with the help of a calendar?
The conception calendar is a convenient program that allows any woman to follow her own menstrual cycle and determine the days of risk of unwanted pregnancy. Or, on the contrary, tell you how to determine the optimal time for conception. This is a kind of form, which introduces the first day of the last month. Different colors will indicate the days, the most likely ovulation.
Let's try to figure out how correctly the day of conception is calculated, what factors were taken into account by the creators of the program.
As a rule, ovulation in most women of childbearing age occurs in the middle of the menstrual cycle. Therefore, in the calendar the day of ovulation and a few days after and before it are painted in orange and green. Useless days, that is, days at the end and beginning of the cycle and menstruation are marked in pink.
To find out how accurately it allows you to calculate the term of conception of a calendar, observe your state. During the period of ovulation, sexual desire increases, the discharge from the vagina increases substantially, and the basal temperature increases. To check up approach of an ovulation it is possible and by means of the chemist's test. Ovulation, often accompanied by aching, brief pains in the lower abdomen.
It should be noted that it is difficult to know the day of conception, since the female organism is individual and the result can not coincide by 100%. Especially since two menstrual cycles a year are infertile. So it is inherent in nature.
Determination of the day of conception by measuring the basal temperature
The plotting of the basal temperature chart can greatly facilitate the determination of optimal days for conception. Measurements are carried out in the morning without leaving the bed, and use a mercury thermometer for this purpose by inserting it 4 to 5 cm into the vagina, into the oral cavity or rectally. It is best to measure at the same time, for 5 to 10 minutes.
Constant drawing up of the schedule will allow to notice the period when there is a small decrease in temperature before its rise. Half of the day between falling and rising is considered the beginning of ovulation. The accuracy of the schedule will be in doubt, if these days the woman suffered an inflammatory disease, with a general increase in body temperature. Also, affect the result is capable of a disease of the genitourinary system, a short sleep, drunk on the eve of a drink with alcohol, taking drugs that contain hormones. Often, the accuracy of the temperature profile disturbs sex shortly before the measurement or a simple change in the temperature conditions in the room.
