Telling people at 9 weeks

Erica • Traveling Dog Mom, Solar Energy Wife, Due Nov 6th

So my husband and I want to tell our family and friends on Friday when we are 9 weeks. This is our very first pregnancy. Im almost 27 and he's almost 29. Currently only his assistant and my best friend know about the baby. Is 9 weeks too soon? I know most recommend waiting till 12 weeks, but I've also had a bunch of friends announce it before then and everything was ok. We went to the dr at 7.5 weeks and the heart beat was 140, and all of my blood tests, urine test, and pap came back perfect. Thoughts?
