First IUI this Friday..

I am getting ready to have IUI Friday as long as my ultrasound looks good Thursday (day 16 of my cycle). I took 100mg clomid days 3-7 and will trigger shot with ovidrel Thursday after my ultrasound for IUI Friday. This is our first try with IUI and I am so incredibly nervous/ don't know what to expect/ want more than anything for it to work. Any advice out there on how to cope/ what to expect?
