For one thing most pregnancies are 40 weeks 280 days long but not all of them are. So the due date is always an estimate regardless of an IVF pregnancy or non-IVF pregnancy.

Naegeles rule is what this due date calculator and pregnancy calendar is based on.

. Named after a German Obstetrician who practiced in the early 1800s Naegeles rule predicts childbirth to occur 280 days after the first day of the last menstrual period. Ultrasounds throughout the pregnancy will tell you and your doctor how the baby is growing and the due date can be adjusted based on that.
