I have been taking Ocella birth control for eight months now. I missed a pill for one day (first time I've missed) and got my period the next day even after taking two pills to make up for the day I missed. It has been three weeks now and my period has not stopped despite taking the estrogen. Period is light, but constant, not spotty. I am not pregnant. I made an appointment with my gynecologist, but I'm still wondering what is going on?

Thanks for your input.
