Announcement & miscarriage risk?

I am planning to announce my pregnancy on Friday. I will be 10w&6d then. I have seen/heard the heartbeat 3 times. I am still scared that it may be too early & since I am somewhat a public figure it would be hard to explain if something happened. I haven't had any spotting & everything seems to be going fine according to Doctors. Does everyone feel anxious or should I hold off another 2 weeks? Any suggestions, advice or stories on announcing & having bad news afterwards?
