So my OBGYN gave me Aviane after my son was born, was doing good but then I missed one pill from after taking the pill for over a week and a half and them boom started my period Dec 19 and I'm still on it going on 2 weeks now. Should I be worried? When I first started it was a brownish red color and nexthe day went to normal and now it's like a blackish, redish and brown color. Is these normal, by me missing one pill should have I Started my period or do I need to be worried... please help first time taking birth control ever and not sure what to do
