Hi dstout,

Just wanted to share: Let me first say that about 9 years ago I lost 65 pounds doing Jenny Craig while I was not taking the pill and had no cycle problems at all. I've been on the pill for 6 years now (with no problems) and for the first two cycles after I started Atkins I had mid-cycle bleeding at least a week early and that just started my period. Since then, no problems. I figure it must have been some sort of enzyme/hormone change because I'm still losing weight and taking the pills, but I'm back to normal cycles now.
