so me and my boyfriend have never actually had sex, but we have fooled around like he has humped on me with his clothes off from behind and came and he did this on the 13th and then we messed around like that again on 30th and now my period still hasnt started (supposed to today but normally is later) and i have almost no pms symptoms except for my mood but im soooo stressed because the only reason we dont have sex is because we aren’t ready and dont wanna get pregnant. any chance i am? ps — i had NO implantation bleeding of any kind
