Pregnancy is the term used to describe when a woman has a growing fetus inside of her. In most cases, the fetus grows in the uterus.
Human pregnancy lasts about 40 weeks, or just more than 9 months, from the start of the last menstrual period to childbirth.
Getting good prenatal care and seeing a health care provider regularly during pregnancy are important ways to promote a healthy pregnancy.
