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.
How accurate are IVF due dates?
Due date calculations may vary regardless of whether you conceived naturally or via IVF. Even with IVF and ultrasound measurements, no due date is a guarantee. It’s just a way to provide a window of time in which you are likely to go into labor.
