Pregnancy

Pregnancy is when a woman's body grows a baby. It starts when a sperm and egg meet inside the woman's body. The sperm and egg combine to make one cell. That single cell divides over and over again and eventually makes a baby. After 9 months, the baby is born. During those 9 months, the baby gets bigger and bigger inside the woman's body, and the woman's body changes to make room for the growing baby.
