I've been on tri sprintec (combination pill) for about 4 years now. My period ended this past Sunday and on the same day I was supposed to pick up my new pack and start it that Sunday. I forgot and didn't end up getting it until Tuesday.so Tuesday I took two pills(for Sunday and Monday) and Wednesday I took two pills( for Tuesday and Wednesday). By Thursday I was back on track and Took one pill. Friday I took one pill and Saturday I took one pill. Saturday night I had unprotected sex. Sunday which is today, I took one pill. Would I have been back on track before having sex on that Saturday and could i have had an increased chance of getting pregnant?
