IUI question!🧐💥

Hello ladies! My appointment last appointment before IUI is friday im on cycle day 6 today and will be on cycle day 9. I think the nurse said something about taking some kind of medication but if i read on it it would be ovarian stimulation but im too far into my cycle for these type of meds...... did anyone take meds before IUI treatment? If so wich day of your cycle? Thanks so mich😘
