My boyfriend and I were fooling around (not using any form of birth control or contraceptive) and he accidentally slipped inside of me a little bit; only tip penetration. Obviously he didn't orgasm and we both stopped immediately. This was July 10th. I was supposed to begin my period on the 26th of June. It's now the 28th and I realize it's only two days, but I am FREAKING out. My period is pretty regular. I do not want to be pregnant. I am also supposed to start the birth control pill this month when my period starts, but it hasn't yet. Yes I am a little stressed about my next year in college, and the future, but that's normal for me, so I don't see why that would all of a sudden had an effect. I also saw the gynecologist on the 13th of June and she performed a pap smear. The results were normal and she said everything looked fine. PLEASE HELP! I'm so scared. : (
