Pregnancy
Updated:Pregnancy is the term used to describe the period in which a fetus develops inside a woman's uterus. It usually lasts about 40 weeks, or just over 9 months, as measured from the last menstrual period to delivery. During this time, the fertilized egg develops into an embryo and then a fetus.
Additional Information
Pregnancy is divided into three trimesters, each lasting about 3 months. During pregnancy, a woman's body goes through many changes as it supports the developing baby. This includes hormonal changes, weight gain, and the growth of the uterus. Regular prenatal care from a healthcare provider is important for monitoring the health of both the mother and the developing baby.
