I'll look for some links, but try some searches. Atkins screwed up my TOM horribly. I actually changed my pill to correct the problem. What type of pill are you on? I was on tricyclene. My problem was that 1/2 way through my cycle, I would receive my visit from TOM and he wouldn't leave for three weeks. I went through this for two months (thinking it may get back to normal), but after 6:8 weeks having TOM and was fed up. I know your's has only a couple days early so I don't think it's anything to worry about. Now, if say forget to take my pill - oh my, TOM comes marching in immediately. It's so strange. I 've never had that problem before (if I missed 1 day, by say 12 hours). I'll look for some of those links and get back to you.

Good Luck,
Erin
