IUI success?

I am having my first IUI done on the 25th. Husband and i have been trying for over 2 years, 1 MC and just recently had surgery for endometriosis. I also have a tilted uterus. I will be taking clomid starting CD 3 then menopur on CD 9, ultra sound on day 13 and if all looks good an overdryl shot to make me ovulate. I would then go in for the IUI 2 days later. Has anyone had this procdure and had success?
