1. What is India EDD Calc?

India EDD Calc (Estimated Due Date Calculator) calculates pregnancy due date based on the last menstrual period (LMP) using the standard formula of LMP + 280 days. This method is widely used in India for estimating delivery dates.

2. How Does the Calculator Work?

The calculator uses the standard pregnancy calculation formula:

Where:

• \( EDD \) — Estimated Due Date
• \( LMP \) — Last Menstrual Period date
• \( 280 \text{ days} \) — Standard pregnancy duration (40 weeks)

Explanation: This calculation method, also known as Naegele's rule, assumes a 28-day menstrual cycle and adds 280 days (40 weeks) to the first day of the last menstrual period.

3. Importance of Due Date Calculation

Details: Accurate due date estimation is crucial for proper prenatal care, monitoring fetal development, planning for delivery, and identifying potential pregnancy complications.

4. Using the Calculator

Tips: Enter the first day of your last menstrual period in the date field. Ensure the date is accurate for the most precise due date calculation.

5. Frequently Asked Questions (FAQ)

Q1: How accurate is the LMP + 280 days method?
A: This method provides a good estimate but actual delivery dates can vary. Only about 5% of women deliver exactly on their estimated due date.

Q2: What if my menstrual cycle is not 28 days?
A: For women with longer or shorter cycles, the calculation may need adjustment. Consult your healthcare provider for personalized calculation.

Q3: Can ultrasound provide a more accurate due date?
A: Yes, early pregnancy ultrasound (especially first trimester) can provide a more accurate due date estimation than LMP-based calculations.

Q4: Is this calculation method specific to India?
A: While the formula is universal, this calculator is designed with Indian healthcare practices and terminology in mind.

Q5: What is considered a full-term pregnancy?
A: A pregnancy is considered full-term between 37 weeks and 42 weeks. Delivery before 37 weeks is considered preterm.
