One of my friends changed her profile pic to one of her bump and status to "...is wondering whether it's normal to have such a big bump at 14 weeks" I quite like that idea.
She's mega skinny though, and her bump was pretty blooming obvious, so I'm assuming she was only announcing to us that she hadn't seen for a while.
I think I'll tell the people that matter first, but sure I'll have it on facebook at some point after that. Don't want to tell anyone till the scan, want to make sure everything is ok first, say me paranoid but....
