When did you first tell people that you were pregnant, and who did you tell first? Who wanted to wait more, you or SO?

We just found out last weekend that I'm pregnant, and saw DH's grandmother, dad, and brother the next day-- that was way too soon for us to say anything. Then we saw my family for Thanksgiving, and I told my one sister, but that was it. I wouldn't have minded telling my parents too, but DH really doesn't want to tell anyone else until my first Dr. appointment on Dec. 17, which means we will tell his family at Christmas, but we won't see my family again until January. I'm fine with it-- this week seemed too early to tell anyone, but January seems SO far away now! (we live kind of far and don't see either side often, hiding it will not be an issue).

I'm curious when other people told and if other SOs were more cautious than the actual pregnant person?
