Peter?
I like it. I think it's one of those names that hides in plain sight, so to speak. Everyone knows it, but I don't know many who are called it. I also don't mind the nn Pete, and there are a lot of names that put me off b/c of the nn possibilities (I like Christopher but not Chris, Thomas but not Tom, etc.)
The only thing that worries me is that here (don't know about there) it's a minor euphamism (sp?) for penis. So...
Anyway, not pregnant, so it's not an urgent question. I'm just getting my ducks in a row for next time! :)
