Explanation: This calculation projects forward from your current pregnancy stage to estimate when you'll reach the standard 40-week full-term pregnancy duration.
Details: Accurate due date estimation helps in prenatal care planning, monitoring fetal development milestones, and preparing for delivery. It also assists healthcare providers in scheduling important tests and screenings at appropriate times during pregnancy.

Q1: How accurate is this due date calculation?
A: This provides an estimate based on standard calculations. Actual delivery dates can vary by ±2 weeks from the estimated due date.
Q2: What if I know my last menstrual period (LMP)?
A: For more precise dating, use your LMP date with your healthcare provider, who may also use ultrasound measurements for confirmation.
Q3: Why is 40 weeks used as the standard?
A: 40 weeks is the medically accepted duration for a full-term pregnancy, calculated from the first day of your last menstrual period.
Q4: Can my due date change during pregnancy?
A: Yes, healthcare providers may adjust your due date based on ultrasound measurements, especially if there's a significant difference from LMP-based calculations.
Q5: What percentage of babies are born on their due date?
A: Only about 5% of babies are born exactly on their due date. Most births occur within two weeks before or after the estimated date.
