TTC but no baby yet

My husband and I have been trying to have a baby for 5 years now and just last year started seeing a fertility specialist. I can't do <a href="https://glowing.com/glow-fertility-program">IVF</a> yet because I have a problem where I keep bleeding and my doctors have no explanation as to why. I've done many tests and still no answers and still no pregnancy. I was diagnosed with pcos which caused a rapid increase of weight. I gained 50 pounds in a year. I figured I could just live with this extra weight but just last month after another visit with my fertility doctor she said I should try losing weight to see if it helps (as if I haven't tried yet). I've been exercising 5 times a week for about a month now. It's been so hard physically and mentally but we really want a baby.. anyone else going through this same struggle?? I only lost two pounds so far.
