I could really use some insight. Ttc for 4 years last year was diagnosed with unexplained infertility. Did alot of tests. Surgery cause I had 2 polyps in my uterus. I'm 335 5"9 and feeling super down thinking I'm to "big" for fertility

We did our first round of letrozole in march. It ruined me mentally when I got that negative. So yes I did gain weight. I was sad. Im getting better mentally. Anyway hubby and i talked and we want to start treatments again in January. I guess I just need a friend who's been where I am now. Around the same weight. And going through fertility treatments. Help
