The common term is pregnancy. The technical term is gestation.
The embryonic period extends to the end of the eight week. After the embryonic period (8weeks), the developing human is called a fetus.
The gestation period (about 266 days in humans) is when the embryo is developing inside the womb.
In the very early weeks, the developing baby is called an embryo. Then, about eight weeks onward, it is called a fetus, meaning 'young one'it is a three-month period called a trimester
The period during embryo development when the embryo is alive but not actively growing is called the embryonic diapause. This is a state of suspended animation that allows the embryo to delay development until environmental conditions are more favorable for survival.
In the first two months, the baby is called an "embryo". But from that period on to the birth, the baby is called a "fetus."
Exposure to a harmful substance during the first trimester of pregnancy is most likely to damage many organs in a developing embryo since this is the period when organs are forming. Any disruption during this critical period can have long-lasting effects on the overall development of the fetus.

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.
The embryonic period are the first eight weeks of development of the child, beginning with fertilization. During this period, the embryo undergoes an amazing transformation from a single cell to a recognizably human embryo. In the mid-twentieth century, George Streeter devised a commonly used embryo classification system by dividing the embryonic period into 23 stages. The embryonic period is followed by the fetal period, which encompasses the remainder of theprenatal development.
An embryo is no longer called embryonic once it enters the fetus stage. Typically, this period occurs around eight weeks after initial fertilization inside the woman's womb.
The germinal period typically ends around two weeks after fertilization, when the fertilized egg implants into the lining of the uterus. At this point, the developing organism is referred to as an embryo.
