Announcing my pregnancy

A
Im 8 weeks with my first pregnancy and I always said to myself that I would wait until I was safely out of the first trimester to announce to everyone that i was pregnant. Ive told all of my family and my man has decided that if everything goes well at my 9weeks+2 scan that we would post on facebook to let all of our friends and extended family know. No matter what happens, I want the world to know that im growing life inside me, its getting harder and harder not to want to tell everyone. Would you announce just now or would you wait until you had the ultrasound picture? And if anyone has any announcement stories they would like to share I would be happy to hear <3
