IUI HELP!??

Hi! Anyone had trigger shot + IUI?

I was told to do trigger tonight 9pm & then iui 10:30am on Saturday that’s about 37.5 hours apart. I heard it IUI is supposed to be done 24-36 hours after trigger. I messaged the clinic but they haven’t responded & im freaking out. Has anyone had their iui that apart? Will possibly be 38 hours apart since I’m sure I’ll be waiting in the waiting room also.
