I told my parents as soon as we found out, and we'll have told all of our close friends and family by around 6 weeks. (I'm telling a bunch of friends this weekend). I know it's early, but I'd be the kind of person that needs a support net if the worst ends up happening. I can't imagine suffering through a loss without having anyone to talk to about it. But I won't be posting anything on facebook or livejournal or other forums I visit until much longer.
