At the end of April I had sex for the FIRST time and everything was fine and nothing happened but then in May I had I guess "unprotected" sex , my boyfriend just put the tip in but he still went in and I told him to pull out I didn't feel comfortable unless he had a condom then we just rubbed on each other naked and then I missed my period for 2 days then finally got it but it was brownish at first then I started bleeding cramps and everything I use tampons I've always had but then I used one at least by 3 or 2 i took it out and only the tip was bloody and brownish I don't know what it means or if I'm freaking out because I don't have a heavy flow ! Can someone give me answers please it would help a lot to know if I'm just being crazy or if it really means something
