weight loss with PCOS

Ladies that have PCOS and struggle with missed periods & being insulin resistant, have any of you lost weight and gotten pregnant? I'm changing my eating habits and working out in hopes I'm able to increase my chances of concieving and doing so without IUI or IVF. (I'm thinking I'll still need Clomid or Letrozole since I don't ovulate) I'm 5'5 and currently weigh 172 pounds. I'd love to hear positive stories. 😊
