The word 'fetus' is used to describe a developing human or animal inside the mother's womb. It is used mainly in a medical context, such as when discussing pregnancy or prenatal care. When a woman is pregnant, her developing baby is called a fetus until it is born. So, if you're in a situation where you're talking about a pregnancy or discussing the health of an unborn baby, you might use the word 'fetus'.
