First Try at IUI!

Crystal
My husband and I had our consultation at a fertility clinic today. Everything was great with me and fortunately I got my positive OPK today. So, we are going in tomorrow morning to try IUI. My husband has a varicocle and low count as well as motility. We have had sex the past three days and they checked my CM for sperm and did not see any. I'm really hoping he still has sperm. It's been four years since he had a SA. We will find out tomorrow! I'm so nervous and excited! I know conceiving on the first try is rare but I'm happy we are taking the next step. Has anyone else had luck with IUI with low sperm count?
