How to announce your pregnancy to colleagues?

In my first job, when one of my colleague was pregnant she informed our lady manager first. We used to have short weekly team meetings. So after one such meeting, the manager announced that she also has a good news to share. The details like which month all was then shared by the colleague. Some colleagues have shared themselves as well during the meetings if they are expecting or getting married or getting HDB key (any good news in short) 😊 But we were really close group. The news will get spread to other teams eventually

I only told a few of my colleagues cause they somehow knew. The rest eventually knew when they saw my baby bump. Didn’t announce pregnancy on social media cause it was my first and I wanted it to be an intimate one. Depends on individual on how you want to announce it; either casually texting the group or when you guys meet. Don’t have to be so formal.. it’s a happy news to share! It’s exciting if I were to find out about my colleague’s pregnancy too 😊

personally I don't find the need to announce my pregnancy to people out of my immediate family. when I got pregnant, I informed my immediate superior for ML purposes and so he understands when I need to take MC once a mth for check up. for everyone else, I don't deny when asked, but I don't announce it either.. slowly everyone knows through office gossips 😅

And for my overseas friends whom I'm close with I shared through a WhatsApp group chat. Just posted a pic of "Baby in progress" with the caption 'to be completed by April 2021' 😊 Some replied in the group message while some replied individually. Accordingly I shared details like which week currently, how's the feeling, etc etc. 😊

Hahaha i just told my colleagues “guys, im pregnant”
