Pregnancy is one of the most interesting and pleasant changes in life. This time always bears a huge number of various questions. When the woman is pregnant, she by all means all wants to know about the present state. How the kid on weeks develops as she changes, and, of course, there is a wish to know when the child is born.
Definition of date of childbirth proceeding from date of the last periods
It is rather simple to calculate pregnancy term. It can be done as follows: by first day of the last monthly add 40 weeks, as a result you receive approximate date of childbirth. On ultrasonography which normal becomes three times (in 12-14, 22-24, 34-36 weeks) the doctor also surely will deliver you a certain term how the fruit develops. Most often this date coincides with calculations according to this scheme.
Let's say that the first day of the last monthly on March 3, 2014. We add 40 weeks and we receive on December 8, 2014.
Calculations for date of conception and day of an ovulation
It is also very simple to determine date of childbirth by date of conception. The organism of the woman is capable to conceive the child only in the period of an ovulation. The ovulation is an exit of a mature ovum from an ovary which occurs in the middle of a menstrual cycle. Knowing date of an ovulation it is rather easy to count date of the forthcoming childbirth.
Some women can feel the ovulation moment. It is expressed in the pricking or pulling feelings in the lower part of a stomach and increase in number of allocations. Precisely it is possible to define date of an ovulation by means of ultrasonography. If you do not know exact date of an ovulation, then just calculate the middle of the menstrual cycle and add by this day 280 days. For example, if your cycle makes 28 days, then approximate date of an ovulation falls on 12-14 day. Add to this date 10 lunar months (as makes 280 days), and as a result you receive approximate date of birth of the kid.
If you decide to calculate date of future childbirth on day of conception, then this option will be even more reliable, especially in case in the last cycle you had a single sexual intercourse. However it is necessary to remember that day of conception can not coincide with day of sexual intercourse. The fact is that spermatozoa can remain in the woman's organism a "live" state several days. For example, if sexual intercourse happened in the 10th day of a menstrual cycle, then the ovulation and process of conception could happen also for the 12th day.
Making calculations, you remember that childbirth can begin not precisely in time, and can occur for two weeks sooner or later. Quite often and happens. This situation is quite widespread, but nevertheless it is desirable to know approximate date of childbirth as much as possible to secure itself in such crucial moment of your life.
