The duration of a human pregnancy is the period between conception and birth. The average length of a human pregnancy is 280 days or 40 weeks, calculated from the first day of the woman’s last menstrual period (LMP). However, it is important to note that normal pregnancies can range from 240 to 280 days.
Knowing the duration of a pregnancy is important for several reasons. It helps healthcare providers estimate the baby’s due date, which is essential for planning prenatal care and delivery. Additionally, understanding the stages of pregnancy allows healthcare providers to monitor the baby’s growth and development and identify any potential complications.
