How to Use the Pregnancy Calculator

Our pregnancy calculator uses your last menstrual period (LMP) to estimate your due date and track your pregnancy progress. Simply enter the first day of your last period, and we'll calculate important dates and milestones.

What You'll Get

  • Due Date: Estimated delivery date (40 weeks from LMP)
  • Gestational Age: Current pregnancy duration in weeks and days
  • Trimester Information: Which trimester you're currently in
  • Conception Date: Estimated date of conception
  • Pregnancy Milestones: Important developments and appointments

Understanding Your Results

The pregnancy calculator provides estimates based on a standard 28-day menstrual cycle. Your actual due date may vary, and ultrasound dating is considered more accurate, especially in early pregnancy.

Important Notes

  • Only about 5% of babies are born on their exact due date
  • Most babies are born within 2 weeks of the due date
  • First pregnancies often go past the due date
  • Multiple pregnancies typically deliver earlier

When to See Your Doctor

Schedule your first prenatal appointment around 8-10 weeks of pregnancy. Your healthcare provider will confirm your due date with an ultrasound and provide personalized care throughout your pregnancy.
