How can I calculate my due date after donor-egg IVF?

By Andrea Rodrigo B.Sc., M.Sc. (embryologist).

In general, when donor eggs have been used, pregnancy due date calculators work by adding two more weeks to the date of the embryo transfer. It allows us to copy the process followed in natural pregnancies, where we start counting from the first day of last menstrual period. In principle, embryo implantation occurs around 2-3 weeks before the last menstrual period.
