The embryo attaches to the placenta when it reaches the uterus very early in a pregnancy.
Placenta
The placenta is completely formed by 10 weeks, by the joining of the decidua basalis (maternal side) and chorionic villi (fetal side). The chorion and amnion are the placental membranes. The Chorion is the membrane furthest from the embryo, and the amnion in the inner layer that is closest to the embryo.
