Immediately after fertilization, the egg is called a zygote.  It is called a zygote until it divides into 16 cells. Embryo is first stage of the zygote’s development where its cells multiply to form their designated functions (differentiation), while fetus refers to a point in the embryo’s development where it takes on a more human form, and some bodily functions begin to work.
