announcing too early?

Victoria • My first baby was born 12.12.17 💙 Roman Anthony
We are currently 6 1/2 weeks and so far everything looks fine, although we haven't seen a heartbeat yet the doctors did not seem worried and just said it was too early. We have another ultrasound at 8 weeks where we are hoping to see a strong heartbeat! We would love to announce that day if everything is going well! What do you guys think ? Too early to announce at 8 weeks?
