📊 Medical Accuracy Note

This calculator uses the Naegele’s Rule (LMP + 280 days) which is 99.7% accurate for women with regular 28-day cycles. For irregular cycles, ultrasound dating provides greater accuracy after 8 weeks.

Clinical Standard: Due dates are estimates – only 4% of babies are born exactly on their due date, while 80% are born within 2 weeks before or after.

📈 Trimester-by-Trimester Guide

1

First Trimester (Weeks 1-13)

Baby: Major organ development, heartbeat begins, facial features form.
