My friend and I we were messing around in his car, it started as a blow job and then we were going to have sex, but he was too big. He had the condom on at first, but I was in pain and he said it might be because of the latex sticking because I don't get very wet. We tried two different positions but neither worked so I finished with a blow job. I'm concerned about the precum because my periods late. It was my first time, and I read online that it could be the stress on me mentally or my body could still be in shock from it.
There is a slight possibility you could be pregnant, but it's pretty slim. It could very well be that stress has made your period late. Give it a few days more and see if your period starts. If not, you should take a home pregnancy test in about 2 weeks.
