The blastocyst then forms an embryo which is the early stage of the formation of the little one inside the mother’s womb.

This embryo then changes to a fetal and finally enters the first stage of baby. This baby inside still in its blastocyst form travels through the fallopian tubes of an ovary and attaches itself to the placenta or wall of the ovary. There through nourishment from the mother it starts to form vague shapes eventually resembling a baby.
