Advice/positivity or success stories please

We have been ttc over two years. Went to the fertility doctor in February and all tests came back fine for my husband and I. So we are unexplained infertility. We tried clomid in April just to give more eggs since I already ovulate on my own. There were 2 big follicles and 2 small ones. Didn't get pregnant and I got a cyst on each ovary from the clomid. They also found a polyp in my uterus so I had surgery to have that removed. So now I am waiting for the cyst in my right ovary To go away to try IUI. Definitely not doing clomid again since it gave cysts. Going with femera. I'm just frustrated that nothing is wrong but it's not happening!
