Understanding IVF Due Dates

Unlike natural conception, where the last menstrual period (LMP) is often used, IVF due dates are determined with greater precision, thanks to the controlled environment of the In Vitro Fertilization process. The date of embryo transfer is the key to calculating your estimated due date (EDD).

How to Calculate Your IVF Birth Date

Here's how it works:

  • 3-Day Embryo Transfer: Add 263 days to your transfer date.
  • 5-Day Embryo Transfer: Add 261 days to your transfer date.

Alternatively, use our comprehensive Pregnancy Calculator and Ovulation Estimator, which offers this functionality built in. Pregnancy calculators that are used to calculating due dates can also help if you know that you became pregnant without IVF

Factors Affecting Your IVF Due Date

While the transfer date provides a solid foundation, certain factors can influence the accuracy of your estimated birth date:

  • Embryo Transfer Day: Whether it was a day 3 or day 5 transfer, the number of days to add varies.
  • Frozen vs. Fresh Embryo Transfer (FET): While the calculation remains similar, the timing of FET cycles might differ slightly based on uterine lining preparation.

What to Expect: Accuracy and Monitoring

It's crucial to remember that an IVF birth date, like any due date, is an *estimate*. Most babies arrive within a window of a few weeks before or after this date. Regular prenatal appointments and ultrasound scans are essential for monitoring your baby's growth and well-being throughout your pregnancy. These tools can refine the accuracy of your due date as your pregnancy progresses.

Using the Pregnancy Calculator & Ovulation Estimator

Our Pregnancy Calculator & Ovulation Estimator is designed not only to calculate your due date but also to track key milestones throughout your pregnancy. Plus, you can use it to calculate your most fertile days should you wish to try to conceive naturally in the future. The calculator is user-friendly and accessible across all devices.
