Frequently Asked Questions
Why is the IVF due date formula different depending on embryo type?
A standard pregnancy is dated as 266 days from conception. A day-3 or day-5 embryo is already that many days old at transfer, so those days are subtracted from the 266-day count to land on the correct due date.
Why does gestational age count differently from days since transfer?
Gestational age is conventionally measured from the first day of the last menstrual period, which is about 14 days before conception. This calculator adds that 14-day offset plus the embryo age at transfer to your days since transfer.
Is this due date estimate as accurate as a natural conception due date?
IVF due dates are often considered more precise than natural-conception due dates, since the exact transfer date and embryo age are known rather than estimated from a menstrual cycle.
Does this apply to frozen embryo transfers too?
Yes, the same formulas apply whether the transfer used a fresh or frozen embryo, as long as you know how old the embryo was at transfer.
