IVF Due Date Calculation Methods

Understanding how IVF due dates are calculated is crucial for accurate pregnancy tracking. Unlike natural conception, IVF provides precise timing information that makes due date calculations more reliable.

Standard Calculation Methods

IVF due dates are calculated by adding a specific number of days to the embryo transfer date, depending on the embryo's stage at transfer. This accounts for the embryo's age and development stage.

3-Day vs 5-Day Embryos

The calculation differs based on whether you had a 3-day or 5-day embryo transfer. Understanding these differences helps ensure accurate due date estimation.

Factors That May Affect Your Due Date

While IVF calculations are generally more accurate, several factors may still influence your actual due date, including ultrasound measurements and your doctor's clinical assessment.
