Ok. So i'm 16 and I got my period early for the first time. I'm on birth control and my period lasted about 5 days. After it was over, my boyfriend and i had sex. About 2 weeks later i noticed i was bleeding out of my vag. It was very light, like i was spotting. It didn't go through my underwear so i didn't worry bout using a tampon. Then my boyfriend and i had sex again, and it got heavier. And it stayed heavy for a few days so i did have to use a tampon. I don't know if i can be pregnant cause there have been times where i had sex and forgot to take the pill, and i have still not gotten pregnant. I even had cramps like i was on my period. Please can anyone tell me whats wrong with me? i'm to scared to go to the doctors and i know i should and i will when i can get the nerve to tell my mom. i would appreciate the help. thanks!!!
