Amped up IUI?

Kelly
For our second IUI cycle, my RE is having me take 5 mg femara cd 3-7, and he is starting me of follistim injections cd 3 5 7 9. And estrogel sometime in there. Hcg trigger shot prior to IUI. How many follicles did you have?? Do the follistim shots sting? Any of you ladies have experience or words of advice?? Much appreciated :)
