Really want to announce but too early?

I really want to announce on social media that we are expecting but don't know if it's too early. I'm 12w2d and have seen and heart strong heart beat 3 times. I'm just nervous, especially seeing so many ppl on here mention losses at 13, 14, 15 weeks, although I know that's rare. My husband thinks I should just do what I want, but I'll most likely end up being patient and waiting but it's hard!
