Announcing to immediate family!

Hey ladies! I’m wondering when you announced your pregnancy to your family? (Parents, siblings). My family lives about 6 1/2 hours away but they are coming to visit this weekend and I will be 5 weeks. Would you tell them? We are incredibly close so even if something were to happen, god forbid, I would want their support. Just wondering what you ladies think? If I don’t tell them now, then I won’t be able to see them again until the end of April when I will be around 12-13 weeks.
