Patient's question:
NoDoctor's answer:
Generally, gestational age and estimated due date are calculated based on the last menstrual period. For IVF, the estimated due date is calculated by counting 17 days backward from the embryo transfer date. For example: if the embryo is transferred on January 18th and the transfer is successful, the estimated due date would be calculated starting from January 1st, making the due date October 8th.
