A member asked:
Which birth control is the most effective for a female to prevent pregnancy from having unprotected sex?
A doctor has provided 1 answer
Plan B: I assume that you are asking which pill can you take to prevent a pregnancy after just having had unprotected intercourse. If that is the case, and you are within 72 hours of sex (3 days), taking a single pill (plan b) is approx. 90% effective in preventing a pregnancy. There are other pill regimens as well. It is not going to be helpful if you are already pregnant. Good luck!
