1. What is Pregnancy Week Calculation?

Pregnancy week calculation determines the current week of pregnancy based on the estimated due date and current date. This helps track fetal development and monitor pregnancy progress according to standard obstetric timelines.

2. How Does the Calculator Work?

The calculator uses the pregnancy week formula:

Where:

• \( WP \) — Pregnancy week (weeks)
• \( EDD \) — Estimated due date (date)
• \( CD \) — Current date (date)
• \( \left\lfloor \right\rfloor \) — Floor function (rounds down to nearest integer)

Explanation: The formula calculates how many weeks remain until the due date and subtracts from the standard 40-week pregnancy duration.

3. Importance of Pregnancy Week Tracking

Details: Accurate pregnancy week tracking is essential for monitoring fetal development, scheduling prenatal appointments, preparing for delivery, and identifying any potential complications early.

4. Using the Calculator

Tips: Enter the estimated due date (typically calculated from last menstrual period or ultrasound) and current date. Both dates must be valid and the current date should be before the due date for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: How accurate is this calculation method?
A: This method provides a good estimate but may vary slightly from clinical calculations based on last menstrual period or ultrasound dating.

Q2: What if my due date was calculated differently?
A: Always follow your healthcare provider's estimated due date as it may be based on more precise ultrasound measurements.

Q3: Why 40 weeks for pregnancy duration?
A: 40 weeks is the standard duration used in obstetrics, calculated from the first day of the last menstrual period.

Q4: What does the result mean if it shows "Due date has passed"?
A: This indicates the current date is after your estimated due date, and you should consult your healthcare provider.

Q5: Can this calculator be used for multiple pregnancies?
A: While the calculation method is similar, multiple pregnancies often have different timelines, so consult your healthcare provider for accurate tracking.
