PCOS is very common. I've sold Diabetes drugs for years, and doctors (non-OB/GYN) would ask us about whether or not they could use the products for patients with PCOS.
The best advice is really to start researching it. BUT, only research from credible sites such as MayoClinic.com, WebMD.com, the site for the American College of Obstetrics and Gynecology, the American College of Endocrinology.
In addition to your OB, you should see if you can get a referral to an Endocrinologist (if you haven't already) as they'll commonly manage the PCOS as a hormonal vs. gynecological disorder.
Good luck!
