Hi! I too have PCOS. What was said about Glucophage is exactly right. We had been trying to have a baby for 8 years, and my periods were never normal. I finally went to a reproductive endo MD and he put me on Glucophage. To me it was wonderful. Not only did I get pg 6 months later and have a wonderful son, but it was not like taking bc pills with all the added side effects (headache, mood swings, etc.). Let me know if I can help you in any way. Oh, by the way, after starting Glucophage my periods were like clockwork! Hope this helps. Tia
