"So I've only been on the pill for a month and a week and its been good in comparison so the estrogen based birth control I was on previously because I have a sex drive and I'm not flipping out and acting crazy at all - but I keep getting what seems to be my period. I got my period two weeks into the pill and then I got my period again a week later then had a blood free week at the end of the pill pack but I'm coming close to the end of this next week and I'm bleeding again. Is this normal or should I see a doctor? Its really nerve wracking."
