I am 17. This is my 3rd month on birth control. I am sexually active with my boyfriend. We both have been tested and we are free of any STDs. I'm on Loestrin 24. My first month I had a few days of breakthrough bleeding but my period was on time. The 2nd month I had no breakthrough bleeding and everything was on time perfectly. Now this month, I've taken all of my pills on time except one, which I was two hours late. About two weeks to a week ago, in the middle of the package of pills, I had a week of brown discharge. It was light and light brown at first, but it got darker, heavier, and lasted a week. There was some blood too. Now it's time for my period to start. It should have started yesterday, but it hasn't. I'm on the four brown pills and mine has always started on the first one. I know I still have three more brown pills to take before I start my new package. Is this normal since this is only my 3rd month or could the brown discharge be a period or thrown my period off? Help?
