Hello Mummy, which week do u all stop going to office and WFH?

I tried asking my boss to let me WFH 3 weeks before my EDD, but i end up WFH 1 week before my EDD due to lack of manpower. For me, my transportation from home to work is about 1.5hours and sometimes due to peak hours, no one will let me seat. Thus, when near my EDD, i always take grab to work and home.
