  • Second Trimester (Weeks 13–26): Baby growth, movement, and maternal comfort.
  • Third Trimester (Weeks 27–40+): Baby maturation, preparing for delivery, and hospital planning.

  • Prepare for Delivery: Track weeks to organize hospital visits, packing, and birth plans.

Tip: Integrating a Pregnancy Calculator with a week-by-week pregnancy tracker gives better insight into your baby’s growth and maternal health.
