If you had a healthy 10-week scan, would you announce?

I had an elective ultrasound at 9 weeks, 6 days. Heart rate of 170 (we heard and saw with the ultrasound) and everything looked great.  I am 10 weeks and a day today, and I am thinking about announcing this weekend after I have take my little pumpkin photo. I remember my doctor telling me that if I can make it through the 8-9 week mark, then there isn't any difference between 9+ weeks and 12+ weeks with risk since chromosomal abnormalities pop up between 8 and 9 weeks. He said that week was essentially the last big 1st trimester hurdle. What do you think? Safe to announce?
