Anyone do an IUI?

If you've done an IUI how did it go? Did you conceive? What did you feel the day of getting it done? I feel nauseous today ever since I left the dr office, I know it's not pregnancy symptoms, I just feel off. Did anyone else feel like this as a side effect? And when did you take a pregnancy test after an IUI? My dr said to wait until cycle day 32 to test. This wait is going to take forever. 😣😭 I am so anxious to know if this works!
