Needing a buddy!

My husband and I have been trying for baby for about 4 years now. I just got the courage to visit a fertility doctor this year. We found out that my immune system is over active. Other than that I'm ovulating as I should be and my eggs are fine. Hubby's sperm count was also excellent. We did one round of IUI, femara and injections, and decided to wait as we were getting ready to move across country. We are now where we will be permanently and all I can think about is finding a fertility doctor to try the IUI's again. Thinking about this literally takes up my brain all day long. Has anyone else had the immune system issue and had success with IUI?
