IVF Due Date Calculator
Calculate your estimated due date following IVF or FET. (Note: use the conception option and adjust by your transfer type for an estimate).
This page is for general pregnancy planning and date guidance only. It is not medical advice, diagnosis, or treatment. Pregnancy dates are estimates and can change after a scan or advice from your midwife, GP, or maternity team. Always speak to a qualified healthcare professional if you have symptoms, concerns, or questions about your pregnancy.
Calculate Your Due Date
How is an IVF due date calculated?
Unlike a natural conception which is calculated from the first day of your last period, an IVF due date is extremely precise because the exact date of conception or transfer is known.
- 3-Day Transfer: Your due date is 263 days from your transfer date.
- 5-Day Transfer (Blastocyst): Your due date is 261 days from your transfer date.
Important: Always confirm your exact official due date with your fertility clinic or NHS midwife.
