Final answer:
True, premature separation of a normally implanted placenta, also known as placental abruption, can lead to increased bleeding, which is a severe complication during pregnancy.
Step-by-step explanation:
True, hemorrhage in the deciduas basalis leading to premature separation of a normally implanted placenta can indeed increase bleeding. This condition is referred to as placental abruption, which is different from placenta previa. Placenta previa is a condition where the placenta partially or completely covers the cervix, and is also a known cause of antepartum hemorrhage. In the case of placental abruption, the bleeding occurs due to the detachment of the placenta from the uterus, which is a serious complication during pregnancy. Proper prenatal care and medical intervention are vital in such conditions to manage bleeding and ensure the health of both the mother and the fetus.
