My boyfriend and I were messing around one night and I helped him come. I got a little sperm on my hand while helping him clean up. I left and went home and an hour later (at the least) I was still pretty "excited" myself so I used clitoral stimulation to have an orgasm. I was on day four of my period, which usuallly last five days. I also had a tampon in. I know this scenario is not at all conducive with pregnancy, and I still have around twelve days until my period is supposed to start, but I'm tired of stressing out about this. I have been hyper-aware of my body and any little feeling since then, and get nervous all over again when I feel the tiniest cramp or any feeling at all really. I am a third year student going into the medical profession, so again, I know how things usually work, and basically just need someone else besides myself to tell me how ridiculous this notion is and have the facts that I already know to back it up.
