Help! Should I do IUI?

So I found out I had PCOS months before we started TTC. When we officially started trying in March my doctor started me on Clomid for 2 cycles, which didn't work, so now I am on third cycle of Femara (5 cycles all together with no pregnancy). His sperm is normal and my HSG came back normal. I got my follicle ultrasound today and have one 28 mm follicle that will likely release on Friday. My doctor said they usually recommend IUI on rounds 5 & 6 of medicated cycles and then they send me to an RE if I am not pregnant. My husband doesn't want to do IUI but I am kind of I between on what we should do. Does anyone have advise??? I am on the fence. This is the biggest follicle I have ever had.
