I think it depends on how you feel physically and mentally. Physically, are you exhausted easily? Mentally is when you are always worrying on the job, that can also cause stress which isnt good for bub.

WHen i was preggers with DD, my daily routine didnt change much and went to work until 1 week before she was due because I didnt feel any stress or it wasnt too hard to go to work.

See how you feel and heres to a H&H 9mths!!!
