When should I tell! 🤰🏾

My first pregnancy was found out July 18th, 2019. I only told my fiancé,who begged me to take the test. We hid it for weeks from our family and friends. Only to finally tell my mom one day before I found out that I have a missed miscarriage. My second pregnancy was found out September 30th, 2019 and told everyone, to have a chemical pregnancy three days later. So now that it’s my third pregnancy I have told no one. I’m trying to act as if everything is cool. But since Ik I can’t do my “fun girl” things. When is a good time to say “Hey your going to be a DADDY” or “ Hey Ma and Pa, there’s a baby on the way”
