I took birth control pills for my entire reproductive life - with the exception of a few years when I tried unsuccessfully to get pregnant. So, my periods were always regular. Once I went off the pill a year ago, I had one light period and nothing since. So, I can't speak to your situation, but it could simply be a coincidence. During peri-menopause our cycles change (so they tell me, cuz I was always on the pill). I've know several ladies who's periods got closer together and heavier as they got closer to ending altogether. I'm sure it's frustrating as heck to try tracking periods when you aren't sure what to expect. I think I wore panty liners every day for almost a year after stopping the pill, becuase I didn't trust my body not to start bleeding at an inconvenient time!
