I just switched from nuvaring to minastrin I took my nuvaring out a week ago, stared bleeding 3 days ago. Had sex last night and am still bleeding this morning. Took my first pill this morning. Am I protected or did I mess up by not starting the pill the first day I started bleeding and waiting a full week? I have been on aantibiotics until this morning so I wanted to wait until that course of medication was over. Am I at risk or should I use back up for a week? Could I get Pregnut from last night?
