A member asked:
How much older is the gestational sac than the fetus?
A doctor has provided 1 answer
Gestational Sac: The gestational sac is the first ultrasound sign of pregnancy. You will usually see it beginning 5 weeks from your last menstrual period. By 6 weeks you should see the yolk sac and by 6 and 1/2 to 7 weeks the embryo.
