I took the last active pill of my combination pill pack, Sprintec a day late. I only missed one pill and ended up taking it on the Sunday when my period was supposed to start (Week 4 of my pack). I got my period, everything was fine but me and my boyfriend had unprotected sex on Saturday before I was supposed to start my new pill pack. I started the new pack on time but I'm still concerned about missing the last active pill of the last pack. Should I consider EC?
