PCOS and Metformin

Jenn
Hi, I'm pretty new to this app...I'm 27 yrs old and had a miscarriage in February 2014 and my fiancé and I have been trying to conceive ever since. I was recently diagnosed with PCOS and was put on metformin last month and last week my dosage was increased from 500mgs 2x a day to 3x a day. I was wondering if there's anyone else out there who is also diagnosed with PCOS and if you've had any luck with metformin helping fertility?
