Fetus
During the first two months of pregnancy the unborn child is known as an embryo.
The first two months of pregnancy are the most important months of the pregnancy. The heart, brain, and other vital organs begin developing.
After the 8th week, the embryo is called a fetus.

fetus
The uterine tube is called the fallopian tube and the lining is made up of tiny hairlike, fingers called fimbria. The fimbria move the developing embryo along the fallopian tube to the uterus where it will embed itself. Here it will grow and develop until it is ready to be born in about 9-10 months..
After ontogeny there is maturity.
The heart begins to beat at the end of 3 weeks. Our 'reptilian brain' develops within the first two months, but our conscious thought does not develop until six months into the pregnancy.
In humans, the embryo becomes the fetus at the beginning of the 11th week in gestational age (the 9th week after fertilization). This stage starts when the major structures have formed.
The first trimester ends at week 13, when the developing embryo becomes a fetus.
