Hey guys, I need help! I have been on this pill for about 3 months now. My period had been starting on the second white pill. Well, it hasn't started all day and I haven't had any symptoms of a period. Is it possible that it will only be two days with the brown pills? It's been lasting 3-4 days. I took two pregnancy tests but they both came back negative. Please tell me if your period can change from white and brown to just the brown pills?
