IUI success with pcos?

Jessica • My name is Jessica, I am 27 years old. I have PCOS, My sweet husband and I have been blessed after 5 years TTC and many doctors, we have our rainbow twin girls. After 2 years we are ready to try for more❤️
I have PCOS I have been TTC for a year and a half. I have successfully ovulated 4 times on letrozole and am waiting on results for round 5. I had an HSG test and it opened my tubes this last month. My dr wants me to try <a href="https://glowing.com/glow-fertility-program">IUI</a> if this round is another BFN. Has anyone else been through this? Anyone have success with the <a href="https://glowing.com/glow-fertility-program">IUI</a>?
