Plan for your baby's arrival with confidence. Calculate your estimated due date, track gestational progress, and discover key development milestones for every trimester.
Pregnancy is a uniquely phased journey divided into three trimesters, each with its own physical developments and preparations.
Weeks 1–12. The most critical period for development. By the end of this phase, all of the baby's body systems have started to form.
Weeks 13–26. Often the "golden period." Nausea usually fades, energy returns, and the baby's features and gender become clearly visible.
Weeks 27–40. The final home stretch where the baby grows rapidly in size and weight, preparing for its grand debut into the world.
Calculators provide an estimate based on the Naegele's rule. Always verify your progress with an obstetrician and regular ultrasound scans.
