IUI treatments

Has anyone had luck using letrozole, ovidrel and <a href="https://glowing.com/glow-fertility-program">IUI</a>???  This is our first month trying.  I used letrozole for 5 days and had my first ultrasound today.  One of my follicles measured at 9mm.  The docs want to see the follicles at 20mm.  I started the letrozole again for 10 days this time. I will have another ultrasound on August 1st.  If the follicles are at the right size, I will start the ovidrel and then the <a href="https://glowing.com/glow-fertility-program">IUI</a>.  Please let me know your  thoughts:).
