IUI w/ injectable gonadotropins and HCG trigger shot

Angie
So my new RE suggested that we try IUI w/ injectable gonadotropins and HCG trigger shot next month. We have been trying for about a year now so I'm totally up for whatever he thinks. However I just wanted to see what others think of this procedure. How were the shots? Was it successful for anyone? Anyone have twins? Any advice before we get into this next month's treatment? I'm really excited! He thinks injectables are the only thing I should be taking because I ovulate on my own. I have no idea why but I'm keeping my fingers crossed that this will be the month and thing that works for us. Any thoughts or advice are welcome and greatly appreciated :-) thanks!
