A member asked:

How long does plan b stay in the body ? what happens if you take it before ovulation? will the egg come out after a few days ? thanks.

A doctor has provided 1 answer

Effectivness is 72: hours , however the effectives tapers off with time from intercourse. So it is most effective the closer taken after intercourse and less effective as time passes. It suppress ovulation if taken before ovulation. If suppression goes away due to time pass and weakened effectiveness of the drug it is possible that the egg come out from the ovary.
