The germinal stage is the first stage of prenatal development, which lasts for about 2 weeks after conception. During this stage, the fertilized egg begins to divide into multiple cells, forming a mass of cells called a blastocyst, which floats freely in the uterus and has not yet implanted into the uterine wall. The embryonic stage follows the germinal stage and lasts until the end of the eighth week after conception, during which time the cells begin to differentiate into various organs and tissues.
