First round IUI

Just curious... I had my first medicated IUI done yesterday after 6 months of oral letrazole (2.5mg, 5mg, 7.5 mg) only. HSG was normal. Doctor did not recommend any other medications or tests ( other than progesterone labs after suspected ovulation. I see a lot of posts discussing IUI but other monitorings, meds, or trigger shots are given. Anyone have a successful IUI as I described?
