PCOS, Weight & Letrozole

I had my first dose of Clomid May but I didn’t ovulate. My progesterone level was 0.4 and my Side effects were horrible so my doctor prescribed me Letrozole in June. On day 21 I had a progesterone test done and my level was at 9.4. My doctor said she wants to see a level high than 10. I’m currently on my 2 round of Letrozole. So I’m really hopeful this may be THE month!

But I can’t seem to stop worrying about my weight and how it can possibly affect my pregnancy, especially since I have PCOS. I’m 5’6 and weigh 206. I have always struggled with my weight and my doctor has always told me that I need to lose weight in order to get pregnant. Im also on pre-diabetic and take 2-500mg of Metformin. I’m getting back on track to lose weight or at least maintain a healthy life style (eating low carb and clean foods).

Any one had a similar experience and had a successful pregnancy?
