I had unprotected sex for five minutes or so 11 days ago and I've heard such thing as pre cum could get someone pregnant. It was just after I had my last period so I have to wait ages until I get my next period to tell. However, slight things like I'm feeling really tired , tiny strange cramping , and my boobs are tender and achy as hell but the main one is peeing a lot!. I'm extremely underage what are the possibilities of me being pregnant???
