How many weeks is the zygote stage?
Zygotes divide through a process known as mitosis, in which each cell doubles (one cell becomes two, two becomes four, and so on). This two-week stage is known as the germinal period of development and covers the time of fertilization (also called conception) to the implantation of the blastocyst in the uterus.
How long is the germinal stage?
The process of prenatal development occurs in three main stages. The first two weeks after conception are known as the germinal stage, the third through the eighth week is known as the embryonic period, and the time from the ninth week until birth is known as the fetal period.
What’s after zygote?
After fertilization, the zygote continues to divide and morph into a blastocyst. It continues its journey down the fallopian tubes to the uterus. It takes about three days to reach this destination, where it will hopefully implant into your uterine lining.
