confirmed na ba na buntis ka by PT?
if yes, you may use this app to determine your EDD using your last menstruation period. kahit estimate mo na lang ang date. kasi hindi malalaman kung walang date.
another estimate is kung last menstruation mo ay feb, may contact with partner on feb. so 1 month mo ay march dahil hindi ka na nagkaroon.
better if you go to an OB.
