Ready...Set...IVF #4

Okay...so I started BCP 2 weeks ago and added Lupron 2 days later. I hadn't ovualted yet and was on CD 26. I think they were trying to "override" ovulation so that I wouldn't ovulate at all. BUT, I ovulated anyways and had to wait 2 extra days. So I should be starting stims tonight. I also had a laprascopy done last Monday with Dr.Kligman at Cornell. I swore that they would find endometriosis. To my suprise, I woke up and was told NO ENDOMETRIOSIS. So, I was relieved (because who wants something to be wrong?) but was also hoping for some answers. Dr. Kligman wants to proceed with an IUI now after flushing my tubes. I like him but I don't know where all of his optimism is coming from...3 IVF's were unsucessful and now he wants to take steps backwards to IUI? I don't get it.
