Curious about how is the IVF due date calculated? In IVF, the due date is based on the embryo transfer date, not the last menstrual period. Doctors usually add 38 weeks to the date of embryo transfer, adjusting for whether it’s a day-3 or day-5 embryo. This provides an accurate expected delivery timeline. At Prime IVF Centre, our skilled IVF doctor in Delhi uses advanced methods and technology to track your IVF progress and due date precisely. From embryo transfer to pregnancy confirmation, we guide you through every stage with care and expertise for the best fertility outcomes.
