the embryonic stage lasts from implantation until about the eight week of development.

The gestation period is from the development of the embryo to birth. So technically, it covers the entire gestation period.
The embryonic stage is a part of the first trimester. The first trimester is the first three months of pregnancy and the embryonic period ends around week 8 and it then becomes a fetus.
embryonic
it means an early stage
zygote stage, embryonic stage,and fetal stage
The embryonic stage in which cell migration and differentiation occurs is known as a gastrula.
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.
Also known as the third trimester, it is the final stage of the gestation period where the fetus (or fetuses, depending on the animal in question) experience the most growth in body tissues, and lungs begin to develop and start to become functional.
embryonic stage
Before the fetal stage is the embryonic stage. The embryo develops into the fetus.
8 cell stage
The embryonic stage is a typical stage in development for animals that reproduce sexually, and it has stood the test of evolution in several species.
it does not have a function it is just an intermediate embryonic stage
