1. What is Week By Week Pregnancy Calculator?

The Week By Week Pregnancy Calculator By Due Date helps expectant mothers track their pregnancy progress by calculating the current week of pregnancy based on the estimated due date and current date. It provides accurate week-by-week information about fetal development.

2. How Does the Calculator Work?

The calculator uses the pregnancy week calculation formula:

\[ Week = 40 - \left\lfloor \frac{EDD - Current\ Date}{7} \right\rfloor \]

Where:

\( EDD \) — Estimated Due Date
\( Current\ Date \) — Today's date or any specified date
\( \left\lfloor \right\rfloor \) — Floor function (rounding down)

Explanation: The formula calculates how many weeks remain until the due date and subtracts that from 40 weeks (full term pregnancy) to determine the current pregnancy week.

3. Importance of Pregnancy Week Tracking

Details: Tracking pregnancy weeks is essential for monitoring fetal development, scheduling prenatal appointments, understanding developmental milestones, and preparing for delivery.

4. Using the Calculator

Tips: Enter your estimated due date (provided by your healthcare provider) and the current date. The calculator will determine your exact pregnancy week and remaining days.

5. Frequently Asked Questions (FAQ)

Q1: How accurate is this pregnancy week calculator?
A: The calculator provides accurate results based on the dates provided. However, actual pregnancy duration can vary, so always consult with your healthcare provider.

Q2: What if my current date is after my due date?
A: The calculator will show 40 weeks (full term) if the current date is past the estimated due date.

Q3: How is the estimated due date determined?
