Subchorionic hemorrhage is a condition characterized by bleeding between the uterus and the placenta. It can cause vaginal bleeding during pregnancy and is often associated with symptoms like abdominal pain or cramping. Close monitoring by healthcare professionals is crucial to assess the severity of the hemorrhage and its potential impact on the pregnancy. Marginal placenta previa occurs when the placenta partially covers the cervix, increasing the risk of bleeding during pregnancy and childbirth. It requires careful management to prevent complications such as hemorrhage and preterm birth, often involving close monitoring and possibly cesarean delivery if the condition persists near term.
