Iui after failed clomid cycles

Hello all 😊

I am in the process of researching fertility clinics to decide where I want to go to begin my treatment. A little background is that I was diagnosed with unexplained infertility with annovulatory cycles. I took clomid for 6 months. I didn't ovulate on the first round of 50 MG but I ovulate every month after on 100 MG but never fell pregnant. Looking at all the different treatments the fertility clinics offer I am guessing they will start me off with IUI and just wondering anybody else that did iui after failed clomid, what their experiences were like and if anybody had any success falling pregnant. Any responses advice anything welcome please don't hesitate! Thank you!
