I went off of birth control in August 2011 and didn't have my first period until February 2012. Then I had one in July. I had started (re-started) eating primal at the end of June and my period re-appeared in September. Meaning I went from 6 months & 5 months breaks to only 2 in such a short time. In July, my doctor diagnosed me with mild PCOS due to my irregularity and hormone pattern (higher testosterone/out of sync LH) and follicles on ovaries (no cysts though) and I take this much shorter break between periods as a sign that primal is already having an effect on my hormone patterns and body in ways other than weight loss.
