Who hasn't announced yet?

I'm going insane! I'm 6w1 day and I've known for three weeks already! Two sisters and 1 sister in law are the only ones who knows and it's like EVERYONE is announcing on my facebook the past two weeks! My husband isn't even home from the field (military) for another week and we want to be together when announcing! I feel like I'm ready to break! I have no clue how people manage to wait even longer!
