Renee - We tried Sharkeys a few years ago (before IVF) and they were great. Unfortunately we were pretty new to the infertility game and didn't stick with it very long. But I know quite a few people that have had success with them. I know after only a few months on their herbs my cycles started to have some regularity. I would probably go back now if it wasn't for the cost, I would have to give up acupuncture and there is NO way I'm doing that Have you looked up their website?
