I had to start taking birth control early in my teens because my cycle was irregular. At 21, I just stopped taking it, approximately 2 months ago, to give my body a break. I wasn't planning on having any sex, but an ex boyfriend and I did a couple of weeks ago, but we did use a condom. Right around the time my period should have started, I had a few days of brown discharge and minimal blood -- not the way my period usually flows. Any advice?
