IUI with Letrozole

Co

So we just had our latest appointment with our fertility clinic and after going through all of the testing we have “unexplained” infertility. Everything looks great on both ends. Our doctor wants us to go ahead with an <a href="https://glowing.com/glow-fertility-program">IUI</a> while taking letrozole. Has anyone had experience with this? Symptoms? Did you ovulate sooner than normal? I usually ovulate around CD 12-15.
