Human pregnancy is a complex biological process that involves the development of a fetus inside a woman's uterus over a period of approximately nine months. The exact duration of pregnancy can vary from woman to woman, but the average length of pregnancy is typically calculated from the first day of a woman's last menstrual period (LMP) to the birth of the baby.

Healthcare providers use a combination of ultrasound measurements, fetal development charts, and a woman's menstrual history to estimate the due date.
