I have been on Sprintec for about 1 year and a half, and have always been very good about taking the pills everyday at the same time. However, I had gotten my period five days early this month, and Sprintec always made me start on the same day for the 28 day pack. I have taken the pills at the same time, everyday this month so nothing unusual happened in that way. (I didn't miss any pills or take them at different times a day.) I am sexually active, but since my period is early I don't think it means I'm pregnant. This has never happened before! Should I be worried, what does this mean?
