When to tell Parents and In-Laws

Taurus

Hey everyone! I found out I'm pregnant just two days ago, and now hubby and I are debating on when to tell our parents. The catch is that today is my mom's birthday and I figured this is the best gift that I can give her, but I've only just made 4 weeks today, and don't know if that's too early to announce. If I do tell her today, I'd like to tell Hubby's parents next Friday when we see them, but if I don't I figured we could wait until maybe Mother's Day? What do you guys think? When did you/will you tell your parents?
