Q1: How Accurate Is This Due Date Calculation?
A: This calculation provides a general estimate. Actual due dates may vary based on individual factors, and healthcare providers often use more precise methods like ultrasound dating for confirmation.

A: 40 weeks is the standard obstetric definition of full-term pregnancy, based on extensive research into typical human gestation periods.
Q3: What If My Pregnancy Was Dated Differently?
A: Always follow your healthcare provider's due date calculation, as they may have more accurate information from early ultrasounds or other clinical assessments.
Q4: Can Due Dates Change During Pregnancy?
A: Yes, due dates may be adjusted based on ultrasound measurements, especially if early dating scans suggest a different gestational age.
Q5: What Percentage Of Babies Are Born On Their Due Date?
