Delivering the big news...

Hi everybody, well in pregnant with my first baby, 6 wks and 1 day....i was wondering when would be a good time to let my family know that there's a baby o.k. the way...I want to give them a great Christmas present the big news!..our should I wait till I'm almost 12 wks? Which you know they say when its a safe pregnancy!! I was pregnant once but had a miscarriage at almost 3 months and I had told my family when I found out at around 8 wks...I don't know what to do..but my hubby and I are happy and blessed and hope this pregnancy does go well the whole way...
