I've been having sex with the same person since the middle of july. We started off using condoms but then we eventually just didn't care. Because we didn't use condoms, I had to get the morning after pill a few times. Around that time, while we had sex I would bleed. Not after sex, during sex. It was as if I would start having sex, and then in the middle of it, all of the sudden get my period. It happened twice and got us both kind of scared. I told my doctor and she told me that it was abnormal but not to worry about it unless it happens again. Well it didn't so I forgot about it. However, two weeks ago I started taking birth control. Last weekend was the first weekend I was able to have sex because u're suppose to wait 7 days. We had sex on friday and I bled during intercourse and then on saturday morning and I bled again. So obviously it has to do with birth control...Right? I looked up my symptoms online and the only other possibilities I think, is either cervical polyps or cervical cancer. I doubt it's either one. Does anyone have any idea, or has it happened to anyone?
