I m 15 years old, and I think I am pregnant. I am 100% a virgin, I have never been penetrated, and as far as I know my heimen is still in tact. My boyfriend and I have experimented with manual/oral sex, and on one occasion some of his semen got on my pants (I was fully clothed). However, my period is supposed to start on the 7th, and I have been experiencing several textbook symptoms of pregnancy. Is it possible that I am pregnant?
