need words of encouragement please! :/

Hi I am Kara , I am 25 years old , me and my husband have been trying to become pregnant for 5 years now. After about two years of trying , we started to get worried that somthing was wrong. So I went to my obgyn Doctor, at the time I had been off of birth control since I was 19 so it had been a couple of years since I had any added hormones in my system. She told me after blood work that she had never seen estrogen levels that high before, she said that sometimes it's takes a little while to get out of the body system. I was in awe because ever since I was a little girl I have always dreamed of becoming a mommy, but I didn't give my hopes up I have stayed strong. A year after that we still hadn't become pregnant , so I went back to the doctor again , they did blood work , scans, ultrasounds. Thyroid tests. Anything you could think of , and they just shrugged it off like nothing was wrong . they said that some people just have higher estrogen levels than some people and it was nothing to worry about, and on top of that my doctor acted as if she didn't even want to hear me speek like she was tired of me. So I decided to take things in my own hands and call a fertility specialist. That next week we were in the fertility clinic geting checked out. That was the most blood work I have ever did in my life by the way, I think I had passed out twice. Lol. But they were so much more understanding than my obgyn for sure. And I kept telling myself why didn't I just do this in the first place! So me and my husbands tests results came back that we both had a serious micro organism virus in our bodies. And I was in shock ! How could all the testing at the obgyn office come back negative on everything. At that point I was pissed. But I was happy that atleast we got a diagnosis with somthing because in knew I wasn't crazy. Also she said that my hormones were very uneven , my estrogen was still very high and my progesterone was so low that if I was to get pregnant I wouldn't be able to carry a baby. My husbands test passed with flying colors so we were very happy about that. So she prescribed us with some very strong antibiotics and told us not to have intercrorse in any way for a week and a half. That was probably the longest week and a half of my life.  we came back and passed our culture test, she did some more papsmear test on me and told me that I have a backwards uterus and possible pcos and the best option was to do a medicated iui cycle and that first I needed to have an hsg test run to see if my Fallopian tubes were open, because of their not you can't get pregnant. And I won't lie, I was really scared after she told me that. So much that me and my husband said let's give it a few more years . So .... Here we are five years into trying and nothing has happened as usual. It's as if a negetive pregnacy tests are normal for me . It's not even fun anymore , I get tired of taking ovulation tests and tracking everything just to have another negetive tests after another. We've been thinking about finally going back to the fertility clinic , but to be honest I'm still terrified . But I know that if I want a baby or babies I have to do this its my only option. How do I get over this stage fright of being a test subject , can anyone give me some positive words of encouragement to get me through this?
