Can fetal age be more than gestational age?
Then, do doctors go by gestational age or fetal age?
While gestational age is measured from the first day of your last menstrual period, fetal age is calculated from the date of conception.
Also asked, can gestational age be off by 2 weeks?
A pregnancy is formally considered as beginning on the first day of the mother's last menstrual period (LMP). An infant born before 37 completed weeks' gestation is considered premature. It is possible for gestational age to be inaccurate by up to 2 weeks, even with an accurate LMP date confirmed by other tests.
Gestational age is the common term used during pregnancy to describe how far along the pregnancy is. It is measured in weeks, from the first day of the woman's last menstrual cycle to the current date. A normal pregnancy can range from 38 to 42 weeks. Infants born before 37 weeks are considered premature.
