How would I know?

Hi mga mommies!!! Ask ko lang kasi first time mom here, pano ko malalaman na manganganak na ako? Hahaha. I'm still a student and I need to take my subject this term. March due date ko and my class sched is on TTH, 1 subject lang naman na 1hr and 30mins. I'm just scared kasi baka mamaya di ko alam na manganganak na ako. Hahahaha. I'll be attending my class until last week of Feb. :) Thank youuu ♡
