How is the IVF due date calculated?

For Day 3 add 263 days; for Day 5 add 261 days, accounting for embryo age.

What if my embryo was Day 6 or Day 7?

Day 6 add 260 days; Day 7 add 259 days from transfer. Follow clinic guidance.

Early ultrasounds can adjust dates when there is a significant difference.
