Very first iui and in so nervous.

Jaimee
I'm currently on day three of 100mg of clomid. Only two more days of that to go. 
But im super nervous for the <a href="https://glowing.com/glow-fertility-program">iui</a>. I have no idea what to expect. 
I go in on the 23rd to see my follicles and my doctor is having me order the hcg Shot just in case we'll need it. 
What happens then? 
If I don't need the hcg shot will they do <a href="https://glowing.com/glow-fertility-program">iui</a> right then? 
If I do need it how long will they wait to do the <a href="https://glowing.com/glow-fertility-program">iui</a>? 
I'm so excited and nervous and my doctor is giving me vague answers via email right now. Haha.
