Ask for a referall to an endocrinologist- most primaries are not very educated about PCOS in my experience.
Here is a great link about PCOS:

If you feel you fit into this ask for a referall, but if you do have PCOS you'll have to change your eating pretty dramatically- carbs aren't our friends you'll have to change to a south beach type lifestyle. Lean protein, TONS of veggies, and only whole grain carbs and a limited amount of them, also not too much fruit either. I used to eat low fat and high carb and ballooned up to 235 until a doctor finally suggested to me a few years ago I might have PCOS- after getting my thyroid testes and having my ovaries checked, and so on, it was determined I had PCOS. The weight has come off slowly BUT it's still come off and as I've lost weight I've had most of the symptoms go away. I no longer have dandruff, I get a period more often, my skin is clearer, my sleep apnea is less severe, etc.
What your doctors don't realize is that obesity doesn't cause PCOS, PCOS causes obesity.
