Miscarriage after iui

Hi ladies :) my re has us doing and <a href="https://glowing.com/glow-fertility-program">iui</a> with clomid next month. I actually don't have a problem getting pregnant, but I have recurrent miscarriage. He said between the bigger eggs clomid makes, and the sperm washing, it gives us a little extra chance to not miscarry. (Also doing progesterone and baby aspirin) 
So my question is, has anyone miscarried after an <a href="https://glowing.com/glow-fertility-program">iui</a>? Is the chances of a miscarriage lower? Thanks!
