About Pregnancy Calculations

Pregnancy calculations are based on the first day of your last menstrual period (LMP). A full-term pregnancy typically lasts 280 days (40 weeks) from the LMP.

Pregnancy Trimesters:

  • First Trimester: Weeks 1-12
  • Second Trimester: Weeks 13-27
  • Third Trimester: Weeks 28-40+

Important Notes:

  • Due dates are estimates - only about 5% of babies are born on their exact due date
  • Full-term delivery is considered between 37-42 weeks
  • Ultrasound dating may be more accurate, especially in early pregnancy
  • Always consult with your healthcare provider for medical advice
