First IUI

Today we did our first <a href="">IUI</a>.  We have struggled with infertility for over 10 years now. We have an 11 year old but would love to expand our family.  
Just wondering what everyone's outcome with <a href="">IUI</a>.... if it was successful, how many times did you have to do it? 
When did u start checking for the positive test?   
I'm sorry, I'm full of emotions tonight (probably the clomid talking lol)  I'm excited, scared, fearful of disappointment again.   After 132 negative results, I need a positive 
Thanks in advance for all your advice
