My wife just told me today that my vasectomy failed, if you know what I mean.
Oh boy!  Congratulations are in order then?!!  How many kids do you have then? 
We aren't quite to the excited phase yet, but thank you.  I'm sure when the shock wears off we will be over the moon about it.  We have 2 and one (or more) on the way.
I totally get it.  If I found out that I was pregnant right now, I'd pass out and cry for a few minutes and then be happy.  ha ha.  I pray for your wife and her body! he he.
