How to Use IVF Due Date Calculator

2. Enter the transfer or retrieval date. Pick the exact date of your embryo transfer or egg retrieval procedure.

Frequently Asked Questions

Why is an IVF due date different from a natural conception due date?

Because the exact date of embryo creation and transfer is known, the due date is calculated more precisely than the standard 280‑day LMP rule. The formulas account for the embryo’s age at transfer.

Can I use this calculator for a frozen embryo transfer?

Yes, select the embryo’s age at transfer (day‑3 or day‑5) as per your clinic’s protocol. The transfer date is the day the thawed embryo was placed in the uterus.

What if my clinic gave me a different due date?

Follow your clinic’s advice; they may use a slightly different reference. This calculator follows the standard 263/261/266‑day convention widely used in IVF practice.

Is IVF Due Date Calculator free and private?

Yes — it is 100% free, needs no sign‑up, and everything runs in your browser; your data never leaves your device.
