maternity leave can be taken up to 4 weeks before delivery. i dont think you need a gynae letter for this, as long as there's mutual agreement with your employer. you can use the maternity leave calculator on the MOM website as a guide. if not mistaken, once you and your boss are agreeable on the arrangements, you can submit the maternity leave form to your HR from the beginning of your maternity leave.
hi there, do you manage to get early maternity? and how many weeks you get it for?
