About 2 weeks ago my boyfriend and I were fooling around. He was rubbing his penis against my underwear right where my vagina is. Everything was wet there but he didn't cm, it was all precm, and he didn't pee or anything before either. But it felt like my underwear wasn't there. And it felt like he just rubbed it against my bare skin. A few days later I had my period. But I've heard that you could still be pregnant. Now, because I'm super lazy, I feel as though my stomach has gotten bigger, maybe because all I do is eat, class, then sleep. I don't know what's up, some one help me.
