Knowing exactly or at least approximately when your baby will be born is not only interesting, but also necessary, since in this case, doctors will be able to more correctly assess how he is developing, and thus control the situation so that he is born without problems and pathologies.
Instructions
Step 1
The easiest way to determine your baby's date of birth is by remembering the date of intercourse. To do this, simply add 280 days. But it should be borne in mind that sperm in a woman's body can live for several days, so the day of intercourse and the day of conception are not the same thing.
Step 2
Usually the date of birth is predicted by determining the date of ovulation, because only during this period a woman's body is capable of conceiving. Typically, this is the middle of the menstrual cycle. Mark when you last had your period (first day), add 14 days and nine months to that date. This will be the approximate day of your birth. Such a calculation is not accurate, since, unfortunately, a woman's body does not always work like a clock, and your cycle can be not only 28 days, which means that the date of your baby's appearance can differ by several days.
Step 3
Gynecologists, as a rule, use the Negele formula to determine the date of birth. You can also use this method: subtract three months from the first day of your period, and then add seven days. The accuracy of this method, like the one described above, depends on the regularity and length of your cycle.
Step 4
It is believed to be the most accurate method for gestational age. If your period exceeds 12 weeks, the calculation may be incorrect, since all children are already developing differently at this time.
Step 5
An experienced gynecologist can judge the gestational age and give an approximate birth date based on the size of the uterus.
Step 6
If you have an unstable menstrual cycle, and you do not know the day of conception and ovulation, you can use the method of calculating the day of the first movement of the baby. This usually happens during the first birth - at the 20th week, with subsequent ones - at the 18th week. But this method is not taken into account by doctors because sometimes women confuse movement with gas in the intestines. In addition, all pregnant women are sensitive in different ways; however, a minority of women give birth exactly at the time determined by any method. In many cases, the date of birth is influenced by the number of pregnancies, blood pressure, diabetes mellitus, polyhydramnios, etc. Therefore, childbirth continues to be the highest sacrament of nature, even in the 21st century.
