period of carrying a developing fetus inside the uterus
Pregnancy, also known as gestation, is the period during which a fertilized egg develops into a fetus inside a woman's uterus, typically lasting about 40 weeks from the last menstrual period to childbirth. This process involves significant physiological changes in the mother's body to support the growing fetus, including hormonal shifts, increased blood volume, and changes in organ function.
