Announcing to husband today, christmas eve.

I will be 7 weeks tomorrow, managed to keep it a secret this long and I'm announcing our new baby news to my husband later today! I'm so excited and a tiny bit nervous. We will be announcing to my parents tomorrow on Christmas. I don't want to end up crying too much, wish me luck! I just don't know if I should announce to extended family Christmas also or wait another few weeks. I think I will tell them though.
