Me and my boyfriend had unprotected sex on a saturday (second time).He pulled out, but the sperm was near my vagina so I m worried. I wore a pad afterwards just in case of any blood. There was a little so I wore one the next day (a sunday) and there s was a little blood. Then on monday, when I sat down for a while and stand up really quick, I felt something coming out (like blood as if on a period). However, I have been told that it was possible to still have your period even when you could be or already pregnant. I just want to know if I could be? PLEASE ANSWER BACK ASAP
