First IUI yesterday, nerves everywhere.

Hey everyone.  I had my first IUI yesterday, and I'm beyond nervous.  I've been doing some research (trying to steer clear of less than credible sites) and I learned most women require 3-4 IUI's before success. I'm 30, I'll be 31 in March and my husband and I have been trying for about 8 years now.  It wasn't until about 4 months ago that we started in on fertility.  First was two rounds of clomid, and now we're here with our first IUI done and under our belt.  I'm so nervous about NOT being pregnant.  I know I shouldn't stress, but it's nearly impossible.  So I'm trying to fill the next two weeks with as much as I can to get my mind off it.  The idea of going through this again with a negative is weighing very very heavily on my mind.  I'm trying to prepare for it, but the last negative two cycles hit me so hard - I wasn't prepared for it.  Anyone else in the same boat?  Hope everyone is well.
