Successful IUI?

So I talked to my Ob today and we are doing another round of the Letrazole-4th round until our Endocrinologist appt. May 21. She mentioned that more than likely I’m looking at having IUI done. My husband will be getting his tests done as well while we are there. We have been ttc some what natural the past 4 years with the ovulation and hormones the past year with no luck. I kinda figured we were going to have to do something else.

How many have had a success in IUI? Did you have more then one baby?

Tell me everything.
