Day 1 first iui attempt; advice?

So it is day one and I am starting my first attempt at IUI. I’ve reported my first day and scheduled my day three bloodwork and ultrasound. The other frozen half of the ingredients are awaiting with my clinic.

I’m taking the supplements (methylfolate, coQ10, açai, melatonin, vitamin D, prenatal vitamins , and NAD +). I’m drinking pomegranate juice, which I hate for the antioxidants. To those who have had successful IUI procedures, is there any advice? I know it’s a crapshoot no matter what but has to be expected. I am a bit nervous and looking to do everything I can to push this in the right direction of success….
