Hey All,
I am a 19 year old Female. I need someone to try and answer my question. My Boyfriend and i had sex for the first time Sunday (We had it 3 times in the same day). We used lube the 1st time and the 3rd time. I was a Virgin,He was'nt. It bled a little at first then stopped. A couple hours later i went to the bathroom and it looked like my period had started. I just started Birth control about 3 weeks ago, My period would have been expected around the time i started bleeding if i would'nt have been on BC. Some friends have told me that my period had probaley not regulated yet beens its only been 3 weeks since ive started my taking BC for the first time and it was prolly just my period. The bleeding is kinda heavy,But again i have a friend that told me her first period on the pill was heavy. The bleeding has been going on 4 days now. It looks like my period tho,Cuz there is blod clots present. This has got me so worried! Has anyone else ever had an experience like this? Or does anyone else just want to give their 2 cents? Im scared that there could be some kind of damage up there that im not aware about. Please reply! Anything would be appreciated. Thank You!
