I've been on the pill for about 3 years now. Every month I get the my period the same time, pretty much to a T. This month I haven't missed any days taking my pill, and was only late taking it once. For some reason a couple days ago I started getting what seems to be my period but a lot lighter. I was having cramps a few days ago before it started, which is odd because I never get cramps before, during, or after my period. Just curious as to why I seem to be getting my period when I'm not supposed to for another week?
