| From: | To: |
The Pregnancy Week Calculator estimates the current week of pregnancy based on the estimated due date and current date. It helps track pregnancy progress and provides valuable information for prenatal care planning.
The calculator uses the pregnancy week formula:
Where:
Explanation: The formula calculates how many weeks remain until the due date and subtracts this from the standard 40-week pregnancy duration.
Details: Accurate pregnancy week calculation is essential for monitoring fetal development, scheduling prenatal appointments, preparing for delivery, and identifying any potential complications early.
Tips: Enter the estimated due date (typically provided by healthcare provider) and current date. Both dates must be valid and the current date should not be too far from the actual current date for accurate results.
Q1: How accurate is this pregnancy week calculation?
A: The calculation provides a good estimate based on the due date, but actual pregnancy duration can vary. Ultrasound measurements are more precise for determining gestational age.
Q2: What is the normal range for pregnancy weeks?
A: Full-term pregnancy is typically 37-42 weeks. Calculations outside this range may indicate the need for medical consultation.
Q3: How is the estimated due date determined?
A: Due dates are typically calculated as 40 weeks from the first day of the last menstrual period or through early ultrasound measurements.
Q4: Can this calculator be used for IVF pregnancies?
A: For IVF pregnancies, the calculation should be based on the embryo transfer date rather than standard due date calculations.
Q5: What if my calculated pregnancy week seems incorrect?
A: Always consult with your healthcare provider for the most accurate assessment of your pregnancy progress and due date confirmation.
