Your 40-week journey, gamified

Enter your LMP and unlock 8 milestone badges as your pregnancy progresses — from the first heartbeat to full term. Each badge reveals what’s happening with you and your baby that week.

Reminder:Only about 5% of babies are born on their exact due date. Most arrive within two weeks before or after. This calculator is an estimate using Naegele’s rule — always consult your obstetrician for accurate pregnancy dating and monitoring.
