How to calculate gestational age?

/ On : 12:44 PM
Health-Net: Sometimes there are still many pregnant women are confused and do not know how to calculate gestational age that was lived.

At a certain gestational age calculations sometimes pregnant women and doctors are different. This is because the doctors and midwives will begin counting the pregnancy from the first day of her period ended last menstrual period/LMP. Though of course a woman not pregnant at the time.

Calculation of small gestational age in pregnancy since the first day of menstruation ends because most women do not know exactly when they ovulate, but most know when her menstrual period ends, as quoted from babycenter on Saturday June 18, 2011.

Generally, doctors will count as long as 280 days gestation to determine the duedate calculator or birth of the baby. The amount is equivalent to 40 weeks gestation. But those dates are only approximate, and only 5 percent of babies are born exactly on the date of the estimate.

As for the trimester is often regarded as the third month of gestation. Someone will be said to be in the second trimester after 14 weeks pregnant and third trimester when the pregnancy reaches 28 weeks.

Usually prefer to call someone in the month of her pregnancy, in this case is not appropriate to count one month equals 4 weeks. Therefore taken an average of one month for 30 days and 1 week of 7 days.

Gestational age and generally are not exactly 9 months, for example if the first day of last menstrual period she is January 1, then the maturity date is October 8. So the calculation is like 9 months 1 week or 10 days, but she could give birth before or after that date.

World Health Organization (WHO) stipulates that the maximum limit of gestation is 42 weeks or approximately 294 days. If up to that age yet there is also a sign of birth, the pregnant woman is induced to provide stimulation or cesarean birth to avoid problems in infants and pregnant women.

By knowing the gestational age being served, then the pregnant mother can know the development and growth of what is being experienced by the baby. And can better prepare you for the labor.
