Social media announcement

Katie🐠 • Pro-choice. 6-24-14
I'm thinking about letting people on Facebook/ social media know I am expecting I'm gonna be 12 weeks soon and everything is healthy and normal. I'm not worried about miscarriage, I'm worried about how to tell friends/family, scared on what they will think/ react I don't want to be judged. any ideas or stories about how they announced their pregnancy? this is my first btw I'm not married yet
