Ok, I'm a little shy about this but.... I had sex with my boyfriend exactly a week ago. Well, we didn't exactly have sex, basically he was rubbing his penis on my vagina. He didn't even penetrate me and he didn't *** either. Last night I started getting cramps and I had these thick white mucus discharges. Umm, I was reading about getting pregnant through pre-*** and now I'm really scared. And I'm 100% sure we're both STD free. What are the chances of me being pregnant?
