IUI tomorrow!!

B£öśšõms
Hi everyone... I'm on a follistim+ trigger cycle and we had 4 mature and 2 (15mm) sized follicles ( cd13) and triggered the same day (Monday) .. Now waiting for my IUI 36hours post the trigger... Just wanted to ask you ladies with any experience on this-
did u have  a successful IUI ever ? 
how many follicles did you have on your scan?
 Any info would help /advice would be great!
Just very anxious and keeping everything crossed for this cycle before moving on to Ivf  early next year :(
