1. What is Pregnancy Weeks Calculation?

The pregnancy weeks calculation estimates how far along a pregnancy is based on the due date and current date. It helps track fetal development and plan prenatal care.

2. How Does the Calculator Work?

The calculator uses the following formula:

Where:

• 40 — Standard length of pregnancy in weeks
• Due Date — Estimated date of delivery
• Current Date — Today's date
• 7 — Days in a week

Explanation: The calculation determines how many weeks remain until the due date and subtracts this from 40 weeks (full term).

3. Importance of Pregnancy Week Tracking

Details: Tracking pregnancy weeks is essential for monitoring fetal development, scheduling prenatal tests, and identifying any potential complications.

4. Using the Calculator

Tips: Enter the due date (estimated from last menstrual period or ultrasound) and current date (defaults to today). The calculator will show the current pregnancy week.

5. Frequently Asked Questions (FAQ)

Q1: How accurate is this calculation?
A: It provides a general estimate. Ultrasound measurements in early pregnancy are more accurate for dating.

Q2: What if my result is negative?
A: A negative value means the current date is past the due date (post-term pregnancy).

Q3: Why 40 weeks as standard?
A: Pregnancy is typically calculated as 40 weeks from the first day of the last menstrual period (LMP).

Q4: How does this compare to gestational age?
A: This calculation estimates gestational age from the due date rather than from LMP.

Q5: Should I worry if my weeks don't match doctor's estimate?
A: Always consult your healthcare provider. Ultrasound measurements may differ from LMP-based calculations.
