multiple IUI's?

Has anyone had an <a href="https://glowing.com/glow-fertility-program">iui</a> that worked on the first try and then had another one that worked on the first try? I had an <a href="https://glowing.com/glow-fertility-program">iui</a> in December that worked on the first try but that unfortunately ended in a miscarriage at 12 weeks. My RE was very optimistic that the <a href="https://glowing.com/glow-fertility-program">iui</a> will work again just as well as last time but I'm nervous it won't. Just wondering if anyone has experience. I don't always ovulate so they gave me femara with the <a href="https://glowing.com/glow-fertility-program">iui</a> and my husband has a slight motility issue. Thanks for any feedback!!
