Understanding Pregnancy Calculation

How is the Due Date Calculated?

Most healthcare providers use the Last Menstrual Period (LMP) method. This calculation assumes a regular 28-day cycle. The estimated due date is calculated by adding 40 weeks (or 280 days) to the first day of your last period. This is based on Naegele's Rule, a standard medical formula used worldwide.

What is the Conception Date?

The conception date is the day when fertilization likely occurred. In a standard 28-day cycle, ovulation and conception typically happen about 14 days after the start of your last period. Therefore, the "gestational age" of the baby (measured from LMP) is usually about 2 weeks older than the "fetal age" (measured from conception).

Is the Due Date Accurate?

It's important to remember that the "Due Date" is just an estimate. Only about 4-5% of babies are born on their exact due date. Most babies arrive within two weeks before or after this date (between 38 and 42 weeks). Factors like irregular cycles or the date of ovulation can affect the actual date of delivery. Ultrasound scans in the first trimester can often provide a more precise dating.
