I am a virgin and I've never had sex in my life. I do have a boyfriend and the furthest I've gone with him is kissing. There was an incident when we were kissing and he went on top of me, but we were both wearing undergarments and jeans. I wanted to know is it possible to get pregnant this way? Can sperm swim through clothing? Btw, we were in this position for about ten minutes, and I was able to feel his erection. Also, I got my period two weeks after this incident, but it was a few days late. I was feeling queasiness with a lack of appetite and breast soreness during my period. That's uncommon of me. It's been four days since my period and I sometimes feel dizzy, have headaches, and noticed an oil production in my hair and skin. Also, I've noticed visible montgomery glands in my breast. I'm only 18 and I'm terrified to take a pregnancy test. My symptoms are those of pregnancy, but I don't understand how. Can I be pregnant? Or am I stressing out? Please help me, and thanks in advance.
