My boyfriend and I have been having sex for about a year and I've been on birth control for about the same amount of time. We always use condoms and 99% of the time I take my pill at the same time everyday. Last month I had maybe one day of very very light bleeding and a few days of brownish stuff when I was supposed to be on my period (which isn't normal for me). I know the pill sometimes messes with your period but I was wondering if that could count as a missed period and if I'm possibly pregnant. Any thoughts/help would be greatly appreciated.
