📚 Understanding Pregnancy

Pregnancy Term

A normal pregnancy lasts about 40 weeks from the last menstrual period, or 38 weeks from conception. The World Health Organization defines normal pregnancy term as 37-42 weeks.

Due Date Accuracy

Fewer than 4% of births occur on the exact due date. About 60% occur within a week, and nearly 90% occur within two weeks of the estimated due date.

Trimesters

Pregnancy is divided into three trimesters: First (1-12 weeks), Second (13-27 weeks), and Third (28-40 weeks), each with distinct developmental milestones.

Important Note

This calculator provides estimates based on averages for single pregnancies. Results for twin or multiple pregnancies may differ. Always consult with your healthcare provider for personalized medical advice and monitoring throughout your pregnancy.
