TTC for 2 1/2 years with PCOS and Endometriosis. Last two cycles were 48 days and 67 days. Constant cramps and spotting in between. Normally, I only have one or two cycles a year, so that's actually pretty good for me. I've tried Clomid 8 times...nothing. I am in shape, eat well, don't drink caffeine, I take 1,500 mg Metformin, as well as Ovasitol, vitamin D, Omegas. I'm planning to try Natural Progesterone Cream and start off with the "Shutdown Method". Has anyone had success with NPC?
