How accurate is the IVF due date calculator?

Our IVF due date calculator provides a reliable estimate based on standard IVF protocols. The accuracy of this calculator for IVF due dates is high, but every pregnancy is unique, and your healthcare provider may adjust your due date based on ultrasound measurements and other factors.

What's the difference between calculating due dates for day 3 vs day 5 embryos?

Day 3 embryos are at an earlier developmental stage compared to day 5 blastocysts. Our IVF due date calculator adjusts the calculation based on the embryo's age at transfer to provide the most accurate estimate possible from our calculator.

Should I use the egg retrieval date or transfer date in the calculator?

The transfer date is the most critical piece of information for our IVF due date calculator. However, providing the egg retrieval date can help our calculator refine the calculation further, especially if there were any unusual circumstances with your transfer.

When should I consult my doctor about results from the IVF due date calculator?

You should always discuss the results from our IVF due date calculator with your healthcare provider, especially after your first ultrasound. This calculator provides an estimate, but your doctor will consider multiple factors to determine your official due date based on your specific situation.

Frequently Asked Questions

How accurate is this calculator?

Our calculator uses the same methodology employed by fertility clinics worldwide, making it highly reliable. However, every pregnancy is unique. Your doctor may refine your due date after reviewing early ultrasound measurements, which are the gold standard for pregnancy dating.

Why is IVF due date calculation different from natural conception?

Unlike natural conception, IVF provides the exact date of fertilization. Traditional pregnancy calculators rely on estimates based on your last menstrual period, which can vary widely. With IVF, we know precisely when conception occurred, allowing for significantly more accurate dating.

What's the difference between day 3 and day 5 embryo calculations?

Day 3 embryos are transferred earlier in development than day 5 blastocysts. The calculator accounts for this difference by adjusting the conception date accordingly. A day 3 transfer counts as 3 days post-conception, while a day 5 transfer counts as 5 days post-conception.

Which date is more important—retrieval or transfer?

The transfer date is the most critical information needed. The egg retrieval date is optional but can provide additional context for your fertility specialist. For the calculator to work, you only need the transfer date and embryo day.

When should I discuss these results with my doctor?

Share these results at your first prenatal appointment. Your doctor will compare the calculated date with ultrasound measurements taken around 8-10 weeks. This combination of calculation and imaging provides the most accurate due date prediction.
