IVF Due Date FAQs

Q

Why is IVF due date calculation different?

IVF dating is different because the embryo age at transfer is known (day 3 or day 5). That makes it easier to estimate gestational age and due date than last menstrual period (LMP) dating. Many people use this as a due date calculator after IVF because it’s based on a confirmed transfer date.

Q

Can I use this as an FET due date calculator (frozen embryo transfer)?

Yes. This also works as a frozen embryo transfer due date calculator and a due date calculator for frozen embryo transfer. To calculate due date FET (or calculate due date frozen embryo transfer), enter your FET transfer date and select whether the embryo transferred was day 3 or day 5.

Q

Is this the same as calculating from egg retrieval?

Clinics may calculate IVF dates using fertilization timing and embryo age, and some patients reference egg retrieval dates. This calculator is designed for transfer-date dating (fresh transfer or FET), which is a common clinical approach. Always follow your clinic’s medical records for official clinical dating.

Q

Is this an IUI due date calculator?

No. IUI due date calculation typically uses ovulation/insemination timing and may follow different assumptions than IVF transfer dating. If you need an IUI due date calculator, use a dedicated IUI calculator for the most relevant estimate.
