March 7, I had sex with my boyfriend, it was protected. Then March 14, we didn't have an intercourse, just oral sex and then March 23 I had my period, which Im not sure about. I just had a black discharge, it was sort of heavy and a bit grainy. Then I was having a shower, peed and saw a heavy red flow. It was the kind I have during period. Everything lasted for 3 days only. Am I pregnant? :( *** answer ASAP!
