Letrozole & IUI Questions

My fertility dr put me on Letrozole 2.5 mg yesterday (day 3 of my cycle) taking 3 a day for 6 days.. I go back to the fertility dr on cycle day 12 which is 10/29 to check follicles/eggs and if they are mature my dr has advised we will do insemination. I have had 4 normal pregnancies over 7 years ago which didn’t require

IUI or anything but my new husband has low morphology so the dr suggest this was help us go in and get pregnant .. I want to know has anyone experienced an

IUI with taking Letrozole?
