Tired of Trying

It's been over 2 years of trying, and now I feel like the third year is coming up way too quick. I'm losing hope that I'll ever get pregnant. I have uterine fibroids, it took a full year to remove the largest one to potentially enable me to get pregnant. We tried 6 months after the surgery, and then- now I'm not having periods. I don't think I'm ovulating because I haven't had a period since late May 2018. I've told my OBGYN, but she's not concerned at all. "This happens for some women," is what she said. I feel like my hormones are going everywhere, and I'm just wasting time. I will have health insurance next month, so I was thinking of going to the fertility clinic. My husband and I went there before. His sperm has poor morphology, giving him a 4.5% chance of impregnating me- assuming I was ovulating at all. The numbers are low. I really want to experience being pregnant. I'm 35 and I've never had kids, and it's been my dream to be a mother since I was a little girl. I keep thinking about giving up and just adopting. Should I keep trying? Should I give up? I want to hear thoughts on this. Thank you fore reading.
