🤰 Pregnancy Due Date Calculator

How is the Due Date Calculated?

The estimated due date (EDD) is calculated using Naegele's Rule: add 280 days (40 weeks) to the first day of your last menstrual period (LMP). This assumes a regular 28-day cycle.

Pregnancy Timeline:

• First Trimester (Weeks 1-13): Conception, implantation, and early organ development. Morning sickness and fatigue are common.
• Second Trimester (Weeks 14-27): "Golden period" of pregnancy. Baby grows rapidly, you'll feel movements, and energy returns.
• Third Trimester (Weeks 28-40): Final growth and preparation for delivery. Baby's lungs mature, and you'll have regular checkups.

Important Pregnancy Milestones:

• Week 8-10: First ultrasound to confirm pregnancy and due date
• Week 12: NT scan for genetic screening
• Week 18-22: Anomaly scan (detailed ultrasound)
• Week 24-28: Glucose tolerance test (GTT) for gestational diabetes
• Week 36-40: Weekly checkups and preparation for delivery

Pregnancy Health Tips:

• Take prenatal vitamins (folic acid, iron, calcium)
• Eat a balanced diet rich in protein, fruits, and vegetables
• Stay hydrated (8-10 glasses of water daily)
• Get regular prenatal checkups
• Practice gentle exercise (walking, prenatal yoga)
