Frequently Asked Questions

Is IVF due date different from natural conception?

Yes. IVF dates are more precise because the day of fertilization or transfer is known exactly.

What's the typical IVF gestation?

About 38 weeks from egg retrieval or 36 weeks from a 5-day transfer.

Does embryo age affect the due date?

Yes. A 3-day embryo results in a longer pregnancy window than a 5-day or 6-day blastocyst.

Can I use this for frozen embryo transfers?

Yes. Choose "Frozen Transfer" and enter your transfer date + embryo age.

Is this calculator medically accurate?

It uses standard IVF dating formulas but should not replace medical advice or ultrasound-based estimates.
