Ugh why am I like this

So at 6w2d I had my very first ultrasound & she told me everything looked amazing. She could not hear a heartbeat but we could clearly see the little heart fluttering away in there. My husband thought he saw 110 on the screen for a heartbeat but he wasn’t sure (he has no idea what he’s looking at😆) my next appointment isn’t until the 27th where I will official have the ability to hear our little baby. Just out of curiosity, any thoughts on when I should announce our pregnancy? Should I wait or should I just do it & keep praying my little baby is doing perfect still? I’m just a worried person all the time & need some advice.
