due date

The due date, also known as the estimated date of confinement, is an estimation of when a pregnant woman will deliver her baby. While the due date is often estimated as a single date, it can be helpful to consider a range of due dates, since only 4% of births occur on the estimated due date.
 Although there is some debate regarding when pregnancy technically begins, whether at fertilization of the egg (conception), or when the egg adheres to the uterus (implantation), gestational age does not vary based on different definitions of pregnancy since it is based on LMP. In terms of gestational age, pregnancies typically last between 37 and 42 weeks, with 40 weeks often being used as an estimate in calculations.

Disclaimer: This calculator provides an estimate of your due date based on standard pregnancy calculations. Actual due dates may vary. This information is not a substitute for professional medical advice. Always consult with your healthcare provider regarding your pregnancy.
It still uses the average gestational age at birth of 40 weeks from a woman’s last menstrual period, as do the other methods.
In the case of IVF, however, the due date estimate can be made based on LMP, day of ovulation, egg retrieval, insemination, as well as the date of the 3-day or 5-day embryo transfer.
In this calculator, the embryo transfer date is used.
