I started taking a combination birth control pill on the last day of my period, Feb. 22. This is my first time taking the pill, but i had the copper iud before that, which was removed that day. I have been taking the pill everyday at the same time since i started, and its been about 10 days since i started taking it and about two days ago, i noticed light bleeding right after my boyfriend and I had sex, with a condom. The bleeding hasn't stopped and today, i noticed it was heavier. And i know it shouldn't be my period because my last period started on the 16th and ended on the 22, making that a maybe a week between periods.
