What are the name of different stages that the fertilized egg undergoes before it is born?

The fertilized egg undergoes several stages before birth, including the zygote stage, where fertilization occurs; the cleavage stage, characterized by rapid cell division; the blastocyst stage, where the embryo implants into the uterine wall; and the embryonic stage, which involves organ development. Following this, the fetus stage begins, lasting until birth. Each stage is crucial for proper development and growth.
