Baby post

I'm 12 weeks today & I'm high risk from some health problems this is my second child. I was wondering when I should announce the big surprise to other family & friends. My mom is the only person in my family who knows at the moment. I'm getting so unpatient I just wanna spill the news now. ☺☺☺☺☺☺ but I don't wanna miscarry & have everyone bothering me about idk what I should do
