Before I cut the carbs, my hormones were way out of whack, and I had some of the symptoms of PCOS. My cycle was long (like 33-35 days), and I had spotting. Insulin is such a powerful hormone, and it can really wreak havoc with your system. My doc's recommendation was oral contraceptives. Nice. Now, my cycle is pretty much 28 days and is much lighter (never any spotting). No more monthly backaches either -- those were a b*tch.
