So I'm new to birth control and have been on it for almost a month in a half. I skipped my sugar pills the first month so I could skip my period but it decided to show up a few days ago as I'm on my 2nd week of active pills for my second month. I know my body is still adjusting to the birth control so I knew it was a possibility that it would come. Did your period change any from when you were on birth control and when you weren't? Mine is usually much heavier and has much more lining coming out but mine now is pretty light with more brownish colored blood. But I'm also not sure it's a period as I did have unprotected sex on Valentine's Day, but he did not cum in me and I have yet to miss a pill. Should I be worried?
