There are three stages of prenatal development:
- Germinal,
- Embryonic,
- Fetal stages.
- The first two weeks after conception are known as germinal stage,
- The third through the eighth week is known as embryonic period,
- The time from ninth week until birth is known as the fetal period.
What is the order of the growth from fertilization to fetus?
A baby goes through several stages of development, beginning as a fertilized egg. The egg develops into
- a blastocyst,
- an embryo,
- then a fetus.
