Amniorrhea is the medical term meaning amnion flow.
That is correct.
Yes
Amnion is the membrane that covers the embryo. Chorion is the membrane that covers the amnion, the yolk sac, and the allantois. The space delimited by the chorion and the amnion is called amniotic cavity and it is filled with aminiotic fluid. The amniotic cavity has the functions of preventing desiccation of the embryo and of protecting it against mechanical shocks.

The embryo that does not have an amnion is the human embryo. It is a membrane that covers the embryo when first formed. Mammals, reptiles and birds have this feature.
There is no such thing as an "ovarian sac". The amnion is a membrane building the "amniotic sac" that surrounds and protects an embryo.
