Pregnancy Info HOME

A few days ago my girlfriend and I were having sex and we were curious what it would feel like to stick the penis in without a condom. It was only in there for a second and then I pulled out. But I don't know if there was any precum or anything, and that's what I'm most afraid of right now. She was on her period at the time and I was wondering if it was possible for her to get pregnant off of the precum. I hadn't masturbated or had any semen come out that day since I had also peed before we started romping. Also, yesterday she told me she had a stomach cramp and that's where I freaked out. She told me it was from her holding her urine in for so long and so it gave her a cramp. Regardless, I'm super freaked out can anyone help me out.
