1. What is EDD Late Calculation?

The EDD Late calculation estimates the due date for pregnancy based on the late period date, using the standard 280-day gestation period from the last menstrual period (LMP).

2. How Does the Calculator Work?

The calculator uses the standard pregnancy calculation formula:

\[ EDD Late = Late Period + 280 days \]

Where:

\( EDD Late \) — Estimated Due Date based on late period
\( Late Period \) — Date of the last menstrual period (LMP)
\( 280 days \) — Standard gestation period (40 weeks)

Explanation: This calculation uses Naegele's rule, adding 280 days (40 weeks) to the first day of the last menstrual period to estimate the due date.

3. Importance of EDD Calculation

Details: Accurate due date estimation is crucial for prenatal care planning, monitoring fetal development, scheduling important tests, and preparing for delivery.

4. Using the Calculator

Tips: Enter the date of your last menstrual period (LMP) in the date field. The calculator will automatically compute your estimated due date by adding 280 days.

5. Frequently Asked Questions (FAQ)

Q1: Why use 280 days for pregnancy calculation?
A: 280 days represents the standard 40-week gestation period from the last menstrual period, which is the most common method for estimating due dates.

Q2: How accurate is this calculation?
A: This method provides a good estimate, but only about 5% of women deliver exactly on their estimated due date. Most deliver within 2 weeks before or after.

Q3: What if my cycle is irregular?
A: For women with irregular cycles, an early ultrasound may provide a more accurate due date estimation than LMP-based calculations.

Q4: When should I confirm with a healthcare provider?
A: Always confirm your due date with a healthcare provider who may use additional methods like ultrasound measurements for more precise dating.

Q5: Can this calculator be used for multiple pregnancies?
A: While the calculation method is the same, multiple pregnancies often have different gestation patterns and should be monitored closely by healthcare professionals.
