What to tell the family

Krista
The hubs and I are going to visit family this week. I am only 5w6d with our rainbow baby and we aren't ready to tell everyone yet. Typically when we visit I am amongst the wine drinkers. I'm concerned they are going to come to the conclusion of our pregnancy on their own. I have been racking my brain for an excuse to tell them why I am not drinking. Any suggestions? Thanks!
