Where:
Explanation: This calculation provides an accurate due date when the exact conception date is known, which is more precise than calculations based on the last menstrual period.
Details: Accurate due date calculation is crucial for prenatal care planning, monitoring fetal development milestones, scheduling medical appointments, and preparing for delivery.
Tips: Enter the exact conception date in the date picker. The calculator will automatically compute the estimated due date by adding 266 days to the conception date.
Q1: Why 266 days instead of 280 days?
A: 280 days is calculated from the last menstrual period (LMP), while 266 days is from the actual conception date. Conception typically occurs about 14 days after LMP.
Q2: How accurate is this calculation?
A: When the exact conception date is known, this method is very accurate. However, only about 5% of babies are born exactly on their due date.
Q3: What if I don't know my exact conception date?
A: If you don't know the conception date, use a calculator based on your last menstrual period or consult with your healthcare provider for an ultrasound dating.
Q4: Does this account for variations in pregnancy length?
A: The 266-day period is an average. Full-term pregnancies can range from 37 to 42 weeks from the last menstrual period.
Q5: When should I confirm with a healthcare provider?
A: Always confirm your due date with a healthcare provider who may use additional methods like ultrasound measurements for greater accuracy.
