Depende naman po sa inyo yan. If you want to maximize your maternity leave post-partum, then magleave kayo right before your EDD. Pero if you want peace of mind na hindi kayo praning na bigla na kayong maglabor, better na at least 2 weeks before your EDD ☺️
Basta pwede kayo magleave as early as 45 days before your EDD.
