Talk to Gynecologist on No Periods For Months

I am 31, weight 71 height 5 feet 2 inch and married last year and unable to conceive. I always had very less flow of periods, fast weight gain (feels like water retention). Periods were irregular and due to facial hair i got treatment with Diane-35. Periods become regular with that but after leaving i experience same problem again. I am not diabetic but have approximately 5.8 level. Now i am not having periods for months as i gained 8 kg after marriage and have only brown discharge. After my scan in Pakistan dr said i don't have pcos that was ruled out a few years ago by one doctor. Now in dubai too, both radiologist and dr scans show that i am less likely to have pcos but thyroid level is high. I want to take aa second opinion. My dr prescribed euthyrox 50ug and asked me to visit endocrinologist. Please tell me if i can conceive with these hormonal levels and egg reserves. Do my reports show something else than thyroid issue. Will thyroid problem be resolved with medication and i wo
