Telling your workplace on your pregnancy

When at first trimester I am asked to go every 2 weeks. With no choice I informed my immediate reporting supervisors and informed e rest when I reach 3 months (Chinese belief)

I knew at week 8 and shared with my boss/team. But i didnt take much sick leave for my check up days since after some time i switched it to saturdays...

after 1st trimester. so before i told i took annual leave to see doctor 2/3 times max i think. after that I just take mc as boss is already aware

inform direct superior right after confirm pregnancy and try arrange all appointments on Saturday

Told my boss at 3 months. My check-up was usually on Sat so didn't really need to take leave.

I informed after first trimester
