I’ve been doing Atkins for a month now… I’ve lost a lot of weight, I feel so much healthier, and I really feel like this is my niche to achieve the goals I want for myself.
The problem is this diet is seriously messing with my cycle. I started early last month, by a week, and had my lady time for 11 days. Two weeks later, it has started again, and again it is still a week early. Have any other women had trouble with this? I have been looking online and read a few articles about it happening, but I’m not sure if this is permanent change in my body or a temporary adjustment?
