Answer: Abruptio placentae; Placenta Previa
Abruptio placentae or placental abruption is the premature separation of the placenta from the uterus. Individuals having this abruption of the placenta experiences bleeding, uterine contractions, and fetal distress.
Placenta Previa, on the other hand, occurs when the placenta lies low in the uterus and partially or completely covers the cervical opening (cervix).
