When to announce?

Katie
I'm 5 weeks and 6 days and I don't have my first doctors appointment until April 14th. My estimated due date is November 22. Ive told most of my family and close friends already. I was thinking about making my pregnancy "Facebook official" on Easter. I'll be 8 weeks and a few days by then. Is that to early to tell everyone? I've seen alot of mixed opinions on how early you should tell in case of a miscarriage. When are you all planning on telling if you haven't already?
