polycystic ovary syndrome
"My normal cycles are about 44-63 days. I started metformin January 12th 2015 at 500mgs a day with Imodium every other day for the first week. After the first week I start 1000mgs my period was January 5th then by February 6th I started again I haven't had a back to back cycle since 2007. Metformin is definitely effective in some females with polycystic ovarian syndrome."
