I have been taking Loestrin FE 120 for several years now. My doctor writes me a 16 refill prescription so that I can skip my period 4 times a year. I had my period in november, decided to skip in december, and should have started my period for January on Monday. I missed one pill in the second week of the pack in December but took it the next morning when I realized that I missed the pill. My boyfriend and I always use a back up, but my period hasn't started, aside from a smudge. Should a be worried about pregnancy, or am I just freaking out for nothing? I'm never late, hence the worry.
