Congradulation Rocky.
You'll enjoy.  When the time comes post a pic, of the ultra sound 
 
I posted my youngest grand child's first ultrasound on here.  It was immediately replied by someone's ultra sound from a later trimester with the caption "Mine's bigger".  Twas kind of fun.
Have all 7 of mine here from last Friday till after the 4th.  The family room looks like an encampment.
You have many things to look forward to....
