My boyfriend and I had unprotected sex. Both of us are 15, I know it was stupid but it just kinda, happened.. It's been about 2 weeks, since we last had sex and 3 weeks since my last period. He didn't finish in me but there's still the chance of pre-cum I gained a small bit of weight, but I haven't really shown any other signs of being pregnant other than a mood swing today. But I'm absolutely terrified. If I'm pregnant, my Dad will freak out along with the rest of my family. I don't know what to do, I'm crying while typing this. PLEASE HELP
