In brief: 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!
