IVF Due Date Calculator – Find Your Estimated Delivery Date
IVF pregnancies follow a different timeline — so due dates can’t be calculated the same way as natural conception.
This IVF Due Date Calculator helps you find your estimated delivery date based on your embryo transfer date or ovulation/fertilization date.

IVF Due Date Calculation Formula
Depending on the embryo stage, here’s how it works:
| Embryo Type | Days Added to Transfer Date | Equivalent to Natural Ovulation On |
|---|---|---|
| Day 3 Embryo | +266 days | 17 days before transfer date |
| Day 5 Blastocyst | +266 days | 19 days before transfer date |
| Frozen Transfer | Same as above | Depends on thaw/fertilization date |
🧬 IVF due dates are more precise than natural conception because the fertilization date is known.
Example
Embryo Transfer Date: 1 May 2025
Embryo Type: Day 5
✅ EDD: 22 January 2026
✅ Gestational Age (on 5 July 2025): 13 weeks, 3 days
