Getting pregnant could generate feelings of happiness and enthusiasm to many women out there. When you let your family and friends know that you are pregnant, the very first question they would ask you is "When is its due date?" Most of the pregnant women would have a gestational age of nine months, but this is not applicable to everybody and even to you. Throughout the period of pregnancy, the body of the women undergo various changes, which they should be aware of before childbirth. Most of our obstetricians make sure that actual date of delivery is close on the date they have estimated.

Calculating the weeks of pregnancy is not difficult. Actually, one can choose from the several methods available in the computation of due date; however, most of the babies are being delivered earlier or later from the estimated date.

"Gestational age" refers to the age of the fetus inside the womb of the mother. Since the exact date of fertilization is unknown, computing the date of the last day of menstrual cycle is use often as part of the formula until childbirth. Normally, it is forty weeks following the first day of last menstruation.

One way to calculate the weeks of pregnancy is knowing the conceptual period. In the first two weeks of pregnancy is when usually ovulation and fertilization occurs; this begins from the first day of the last cycle of menstruation, and the average due date of pregnancy period is actually 38 weeks.

Probably, the most precise way to verify the gestational age of the infant and compute the estimated date is through corroborating one of the techniques with an ultrasound. This is a non-invasive procedure and could be performed as early as 5-6 weeks of pregnancy. The doctor could obtained most accurate results between 8-18 weeks from the beginning of the last period of menstruation. The relatively fixed delivery date will then be given after the procedure.

Weeks of pregnancy are difficult to compute for those women who have irregular cycle of menstruation, because of that they depend much on ultrasonography. However, if the infant is strangely small or large, even the ultrasound might not give adequate information to the estimation of the weeks of pregnancy and its due date.
