Get tested: See your doctor for a pregnancy test and get a prescription for birth control for the future if you are not pregnant. Discuss the different types and consider what is best for you.

Possible pregnancy: Well, it's kind of late for you to do anything at this point. Plan b would probably be ineffective, although, depends on how many hours after sex it's been. If it's been 48 hours, take it, more than 72 hours, don't.
