When to tell people your pregnant?

So my mom and dad and mother inlaw already know, I told them when I found out because it's nice talking to other people about it during the first trimester! I didn't want to tell anyone else until I was 12 weeks but my husband wants to tell his brother next weekend, I will be 11 weeks when I see his brother and I know it's only a week before 12 weeks but I just don't feel comfortable telling other people yet until I hit 12 weeks. Am I being crazy that I want to wait another week to tell him or should I just say screw it and tell him at 11 weeks? I feel like once we tell his brother then I'm going to want the rest of my family know.

When did you tell people?
