I'm in my third week of the ring and started getting cramps and bleeding as if I had my period. I shouldn't take the ring out until this coming Sunday, where I will then have my forth week off and my normal period. I've been using tampons, which is difficult, because almost always that I pull the tampon out, the ring also slips out. Is it normal to start bleeding in the third week? Also, I had "skipped" my period last month, by directly inserting a new ring after the end of the third week. Could this have something to do with it? Thanks!
