I have been on ortho tricyclen for a little over 4 years. I love it, and have never had a problem with it. I take my pill at the same time everyday. Today, I noticed that when I go to the bathroom and wipe, I have a little bit of brown looking discharge. I have never noticed this before. It isn't heavy, it isn't in my underwear, just when I wipe! Anyway, I am still on my active pills, and I start my sugar pills on sunday, however my period usually starts on wednesday. What do you guys think would be causing this?
