I'm 19, i've been on the pill since I was 14. My boyfriend and I had sex on Saturday, I woke up on Sunday spotting a little and this usually happens when we haven't had sex for a minute and he goes deep inside me. I then realized it was a lot heavier as the day went on, then I saw that I hadn't taken my pill since Friday so now I'm bleeding like a normal period and was wondering when this would stop or should I schedule a appointment with my doctor.
