Estimate an IVF pregnancy due date using retrieval or ovulation date and embryo age at transfer. Confirm the date with your clinic.
Estimate an IVF pregnancy due date using an egg retrieval or ovulation date and embryo age at transfer. IVF dating uses embryo-development timing rather than simply assuming an unknown conception date. This calculator provides a planning estimate and should be checked against the fertility clinic’s official dating record. How to use IVF Due Date Calculator: Enter the retrieval or ovulation date used by your clinic. Select the embryo age at transfer. Review the estimated due date and compare it with the clinic’s documented date. Common uses: IVF calendar planning Embryo-transfer date estimation Preparing questions for fertility appointments Why does embryo age matter? The embryo has already developed for several days by transfer, so dating conventions account for that age. Can my clinic give a different date? Yes. Use the clinic’s official dating method and records for medical care. Is this an IVF medical decision tool? No. It is a date-estimation utility.
