My boyfriend and I dry humped on the 4th of March and the 28th of March and he cummed both times but it didn't get on me either time. I had my last period late February, I think, and I haven't had it since then! I've heard that if you are around a bunch of girls for long periods of time your cycle could get messed up, so maybe that could be a reason I live in a dorm! I am only 5'3 and have am overweight so it's hard to tell if anything is wrong. I'm really scared and panicking because what if!? But we both had on all our clothes! I took a pregnancy test, and it said negative, but it was old and probably expired which could potentially be useless. I'm too embarrassed to go buy a pregnancy test.. Someone please help!
