I have had 12 IUI's, fortunately my insurance covered the monitoring. I just wanted to comment that clomid has a risk of mulitples too, many of the "famous" high order multiples are clomid babies. I used injectible meds to lower my chance of multiple. the dose could be more refined. My dr and I agreed that if there were ever more than 2 good follicles I would not have the iui that cycle, that way I was at a lower risk of having more than 2 babies ( of course the chance of identicles does not change with medication)
