Many women who experience confusion when it should calculate the exact gestational age. It is considered reasonable given up to now there has been no reliable method to determine the exact date of conception in the womb.

To calculate the gestational age of a person, the method is widely used today is by sticking to the date of the last menstrual period. The first day of the last menstrual period is considered as the first day of pregnancy someone. In addition to the layman, it is also used by professional health experts.

In general, a pregnant woman will experience a period of about 280 days or 40 weeks since the first day of the last menstrual period. The presumption that the first day of the last menstrual period as the first day of pregnancy is still considered safe although there remains the possibility of not pregnant until about two weeks later.

Here's How to Calculate Age Pregnancy

To determine the method of calculating the gestational age of a person in detail, the following steps can be done.

A popular way to calculate the age of pregnancy is to determine the date of the last menstrual period before pregnancy. This method is considered the best for women who have menstrual cycles of about 28 days.

At first, specify the date of the first day of the last menstrual period and then add 40 weeks from that date to determine the expected day of delivery. This is based on the assumption that pregnancy is usually undertaken during the 9 months alias 40 weeks or 280 days. By knowing the approximate day of birth Little, then the age of the fetus can be known.

However, this method is rather difficult to apply to a person who had difficulty knowing when the last day of menstruation or for those who have irregular menstrual cycles. To help, a rough estimate can be done based on the prediction of ovulation most women, ie 14 days before menstruation begins. So when someone is having a menstrual cycle of 40 days, then it is likely he suffered fertile period on the 26th day. After that, add 266 days to determine a rough estimate of when the birth of Little.

If the above is considered confusing and deemed not give the right results, then visit a doctor could be a solution. Medical personnel in clinics or maternity hospitals are likely to make transvaginal ultrasound to determine more accurately the gestational age of a person.

Ultrasound accurate results become more accurate if done in the early days of pregnancy. If done when the fetus is more mature age, an ultrasound examination can not provide accurate information regarding the determination of the age of the fetus. Even so, an ultrasound examination at gestational age adults is more helpful in watching whether the fetus is growing properly.

Although calculate gestational age is very important, but do not just stare at it.
