First IUI - What to Expect?

Abbi • TTC #3 with PCOS after loss

I’m undergoing my first IUI on Sunday (fourth cycle of Femara). Wondering what to expect in terms of pain? I underwent an HSG during my second cycle, and it was incredibly painful. Should I expect similar pain with an IUI? Any suggestions for lessening the pain? My PA told me no ibuprofen beforehand like I did before my HSG. If it matters, I have a tilted uterus and have never been pregnant. Feeling pretty nervous!
