🤰 Pregnancy Due Date Calculator

How is the Due Date Calculated?

A normal pregnancy typically lasts about 40 weeks (280 days) from the first day of your last menstrual period (LMP). This tool predicts timeline progress using standard clinical metrics:

• Naegele's Rule: Adds 7 days to the first day of your LMP, subtracts 3 months, and adds 1 year to identify the birth window.
• Gestational Age: Represents how far along the pregnancy is, measured in weeks and days from the LMP date.

The Three Trimesters

Pregnancy is biologically divided into three distinct phase checkpoints:
1st Trimester (Weeks 1 - 12): Period of crucial embryonic growth and organ development.
2nd Trimester (Weeks 13 - 26): Often called the "golden phase" as body fatigue decreases and fetal movements start.
3rd Trimester (Weeks 27 - 40): Final rapid development stage leading up to childbirth preparation.
