I am a Severe Type 2 diabetic and am also trying to conceive. Go to see a reproductive endocrinologist if you have not already. Also- have you asked your doctor about Metformin? It helps your sugar levels over the long term as well as increases fertility in some women. I also have PCOS and until this month (after being treated by an endocrinologist and GYN and taking 100 mg clomid), I have ovulated for the first time in years. Best of luck! Don't give up!
