Due date calculator for fertility patients

Like the pregnancy wheel your fertility specialist, OB or midwife uses, this page will help calculate when your baby is or will be due. The is also referred to as the EDC (estimated date of confinement) or EDD (estimated due date). If you conceive on your own or with the help of fertility drugs or IUI, you should use the last menstrual period (LMP). If you conceive through IVF of any kind, you may use either the retrieval or transfer date to calculate this.


First chose the method to calculate your dates ...

First day of your last menstrual period (Natural conception, fertility drugs or IUI)
Date of your egg retrieval (Fresh IVF)
Date of day 3 embryo transfer (Fresh or frozen IVF)
Date of day 5 blastocyst transfer (Fresh or frozen IVF)

Please note that your due date is only an estimate of when your child will be born. Most babies are not born on their due dates, and your doctor or midwife may change the due date based on ultrasounds.
