I am on birth control and have been for awhile. Last month I started bleeding a little late and was still bleeding during the first couple days of my new set of pills, can that mess with the effectiveness of the pill? This month my boyfriend and I had sex without a condom but he pulled out in plenty of time and I have been taking the pill within the same hour of every day and have not missed one. Today I took my first sugar pill and noticed some brown discharge. Does this mean I'm pregnant?? Please help I'm freaking out!!
