mrsodonnell12:Do you have a really common name? Could it actually be someone elses registry? Have you looked into it?
I have an uber common name, and I can find someone with my name, my due date, but not my area. If all three of those markers in place, I find it highly unlikely it's another person's registry.
OP, that would irritate me as well, but I'm inclined to say you are getting a surprise shower, and if the stuff on the registry is stuff you would probably pick out, odds are, your DH is in on it.
I would register somewhere so you can get the completion coupons, and as a FTM, on the chance people would like to send you gifts. I had a few showers as a FTM, but I also had family that sent gifts after the baby was born and at the baptism, so registries can be helpful even if you don't have a shower. I've had three out of state cousins that I sent gifts to when they had their babies, and I checked their registries first.
