When did you announce your pregnancy??

Aleena
Good morning, ladies!
Just wondering when y'all decided to make the big announcement on social media about your little peanuts. I'm about 8 weeks and our close family knows and we're surprising our grandparents this week with cute cards BUT when did YOU post on Facebook that you were expecting your miracle?? 
I'm super excited but can definitely wait because I love surprising people. 
Any advice is most appreciated!
