fetus
A fetus is an unborn baby growing inside its mother's womb.
When people talk about a fetus, they usually mean it as a stage of pregnancy. For example, if someone says "We just found out we're having a healthy fetus," that means they've had their prenatal test and everything looks good for the baby. Sometimes doctors or medical professionals will use the word fetus to refer specifically to the early stages of development, before the baby starts moving around much.
