When to announce?

I know it’s completely a personal choice of when to announce your pregnancy, but I’m looking for input.

I’ll be 12 weeks on June 9, but won’t have another appointment until I’m 13+2 on June 18. We’ve already seen and heard the heartbeat (188 BPM) and the doctor doesn’t seem to be concerned with anything whatsoever (we used clomid to get pregnant).

I’m DYING to announce and would really like to when I’m 12 weeks, but should I wait until after my appointment?
