I will be 4 weeks tomorrow and I'm already wanting to shout it from the rooftops. I tend to get quite sick early on so don't think I can hide it for long. This is also my fourth, so I know I will show earlier. With my previous pregnancies I definitely announced before the end of the first trimester because no matter what happens I want to celebrate this baby and have the support and joy from my close friends and family. I don't announce on social media until after my baby is born.
