Hey, Whats up? I m almost 17 (Turning June 4th) and my boyfriend and I had protected sex last saturday (I think the 21st). I was on BC for about 2 weeks and he had a condom. Well, its come to about 3 days after that activity and my brain kept thinking that I was pregnant, so I would wake up with a rapid heartbeat and have alot of stomach cramps throughout the day. Today I was feeling a little lightheaded this morning. He says he promised he didn t cum in me but I still feel sick-ish. So, my question is, is it possible that I might be pregnant?
