Gestation for a human embryo typically ends at around 8 weeks of pregnancy, transitioning to the fetal stage. The entire pregnancy lasts about 40 weeks, counted from the first day of the last menstrual period. During the first 8 weeks, the developing organism is referred to as an embryo, after which it is called a fetus until birth.
The gestation period (about 266 days in humans) is when the embryo is developing inside the womb.
The heart is the first organ to form in a human embryo. It begins to develop and beat as early as week 3 of gestation.
The period of the embryo is from fertilization to 8 weeks of gestation. During this time, the embryo undergoes rapid growth and development, with major organs and body structures forming. By the end of this period, the embryo is referred to as a fetus.

An embryo is the early stage of development in a multicellular organism, typically referring to the period from fertilization to the end of the eighth week of gestation in humans. It is during this stage that the basic structures of an organism are formed.
Gestation is when an embryo is inside the womb of female animal. The gestation period is the female's pregnancy, from conception to birth.
If it's a human embryo, about nine months. If you're a mouse embryo, about twenty days. Gestation time in mammals varies species to species, but it's generally safe to say the bigger the animal, the longer the gestation.
The common term is pregnancy. The technical term is gestation.
The embryo will develop into a foetus in the womb.
Fetus
The placenta.
The formation of a human embryo is complete by the end of the eighth week of pregnancy. At this stage, all major organs and systems have formed, and the embryo is then referred to as a fetus.
