I still have 4 active pills yet of Ortho-Tri Cyclen Lo and I started spotting last night after sex on the afternoon if that has anything to do with it? But this has never happened my period is always here on the second day of sugar pills, I've been on these pills for about 4-5 months I'm not sure but what could it be? Is there something really wrong with me? Did the sex have anything to do with it? Or is it just spotting? It's dark red and not so heavy, and when having sex its sometimes dry at the beginning and my boyfriend and I always have this problem, thanks
