Over the counter medicine for PCOS?

Whitney

Okay ladies, I was recently been diagnosed with PCOS. I have been trying to get pregnant for about two years. Had a miscarriage back in November. I'm trying to lose weight to try and get pregnant. But I know I need medicine to help concieve. What is the best medicine I can buy in stores because I don't have insurance at the moment due to job switching. Please help a sister out.
