1. What is Pregnancy Due Date Calculator?

The Pregnancy Due Date Calculator estimates your expected delivery date based on your last menstrual period (LMP) using the standard 280-day pregnancy duration. This India-specific calculator provides week-by-week tracking of your pregnancy progress.

2. How Does the Calculator Work?

The calculator uses the standard pregnancy calculation formulas:

\[ EDD = LMP + 280 \text{ days} \] \[ Week = \lfloor (\text{Current Date} - LMP) / 7 \rfloor \]

Where:

\( EDD \) — Estimated Due Date
\( LMP \) — Last Menstrual Period date
\( Current Date \) — Today's date or any specified date
\( Week \) — Current week of pregnancy

Explanation: The calculation is based on the standard 40-week pregnancy model, starting from the first day of your last menstrual period.

3. Importance of Due Date Calculation

Details: Accurate due date calculation is crucial for proper prenatal care, monitoring fetal development, planning maternity leave, and preparing for delivery. It helps healthcare providers track pregnancy milestones and identify any potential complications.

4. Using the Calculator

Tips: Enter the first day of your last menstrual period and the current date (or any date you want to check). The calculator will provide your estimated due date and current pregnancy week. For best accuracy, use the exact date of your LMP.

5. Frequently Asked Questions (FAQ)

Q1: How accurate is this due date calculator?
A: This calculator provides a standard estimate. Actual delivery dates can vary by ±2 weeks. Ultrasound measurements in early pregnancy provide more accurate dating.

Q2: What if I have irregular periods?
A: For women with irregular cycles, LMP-based calculation may be less accurate. An early pregnancy ultrasound (6-12 weeks) provides the most reliable due date estimation.

Q3: Why 280 days instead of 9 months?
A: Pregnancy is calculated as 40 weeks (280 days) from LMP, which is approximately 9 months and 1 week. This accounts for the fact that conception typically occurs about 2 weeks after LMP.

Q4: When should I confirm my due date with a doctor?
A: It's recommended to have your due date confirmed during your first prenatal visit, usually between 6-12 weeks of pregnancy.

Q5: Can the due date change during pregnancy?
A: Yes, healthcare providers may adjust your due date based on early ultrasound measurements or if there's significant discrepancy between LMP dating and fetal size measurements.
