Answer:
The sperm fertilizes the egg and one cell grows to two, four, eight and so on.
Around day 5 or 6, the blob starts to feature different types of cells. Scientist call this blob a blastocyst. The cells in the blastocyst begins to differentiate.
One week in, it implants into the wall of the uterus. By implanting itself into the womb's wall, the embryo basically hides. Cells destined to become the actual fetus and go on to form the placenta. By day 8, the cells are so sorting and arranging themselves, the fetal cells are condensed together and the some cells will form the interface between the baby and the placenta. On day 10, the whole thing increases in size and bundles of cell starts developing into support structures. At this stage, the embryo can develop its own development with no inputs from the mother tissues. By day 12, the outskirts of embryo are preparing to bind more strongly to the walls of the uterus. Little holes will appear to ready for the mother's blood vessels to start supplying the embryo essential oxygen and nutrients.
By now the embryo is signalling it's presence to the mother via a hormone- the one that pregnancy test pick up- HCG and then the body of the baby starts forming.
