First upcoming IUI

Ashleigh • 33 year old fur mommy - TTC for 3 Years. After 2 failed IUIs and one failed IVF ...We had our 2nd IVF transfer on the 22nd of December! Got BFP 11dpt with hpt and beta. We got our Christmas miracle🤞🏻🙏🏻👼🏻
I know I can ask my doctor but I wanted to hear from you guys. I'm scheduled for my first <a href="https://glowing.com/glow-fertility-program">IUI</a>. What should I expect during the procedure? How long does it take? Is it painful? Postop advice?
