Approximately four days after fertilization, the zygote has about 100 cells and is called a blastocyst. When the blastocyst reaches the uterine lining, it floats for about two days and finally implants itself in the uterine wall around six days after fertilization. This signals the beginning of pregnancy.
A fertilized egg is a zygote for about 3 days. Then it becomes a morula; a couple of days later, it is a blastocyst. After about 2 weeks (from conception), it is an embryo.At 10 weeks, it is a fetus.

When the three derms have distinctly formed. The embryo does not become a fetus until after the end of the embryonic period some six weeks later.
