DH not on the same page

I just had an HSG, and I'll be completing my 2nd round of Clomid this evening. Both tubes are open! I'm scheduled for my HCG and US on Monday, but DH is strongly against an <a href="https://glowing.com/glow-fertility-program">IUI</a> 😤. We didn't have it the first time, and I wish I could convince him. Any suggestions?
