Pregnancy announcement on Christmas??

Okay so I just handmade a ton of Christmas/New Years cards and was going to have a custom announcement done on Etsy and print off a bunch of them to add to the cards but I am not scheduled to have my first ultrasound until the 18th (Monday) and I also want to tell a bunch of my family on Christmas and have a onesie that says “best gift ever” wrapped for them. But now I’m thinking I should wait, I’m 6 weeks along right now with my first baby, and I really want to tell my family but I don’t want anything to go wrong or tests to come back bad, and stuff like that. What did you guys do? I just feel like Christmas is a perfect time because all my family is together at once. I’m super close with all my family I will be with on Christmas, and I’ve already told my parents and his because he couldn’t wait.
