1. What is Pregnancy Calculation From Ovulation?

The pregnancy calculation from ovulation estimates the due date based on the known date of ovulation. This method adds 266 days (38 weeks) to the ovulation date, which represents the typical gestation period from conception to delivery.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• Ovulation Date — The known date when ovulation occurred
• 266 days — The average gestation period from conception to delivery

Explanation: This calculation provides a more accurate due date than methods based on the last menstrual period, especially for women with irregular cycles.

3. Importance of Accurate 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.
