Clinical Causes: Blood clotting disorders such as placenta previa or placental abruption that interfere with normal coagulation processes. Pre-existing conditions like bleeding disorders (e.g., hemophilia, thrombocytopenia). Preeclampsia or eclampsia that can impact blood clotting mechanisms. Infections that cause coagulation abnormalities. Trauma or injury during pregnancy that damages blood vessels. Use of anticoagulant medications during pregnancy. Placental abnormalities affecting placental attachment and blood flow.

Key Symptoms: Vaginal bleeding during pregnancy, which may range from light spotting to heavy bleeding. Abdominal pain or uterine tenderness. Signs of hypovolemia such as dizziness, fainting, or rapid heartbeat in severe cases. Signs of fetal distress, including decreased fetal movements or abnormal fetal heart rate patterns. Possible signs of coagulopathy such as bleeding gums, easy bruising, or bleeding from puncture sites.

Diagnosis Path: Pelvic examination to determine the source and extent of bleeding. Ultrasound imaging to evaluate placental position and fetal well-being. Laboratory tests including complete blood count (CBC), clotting profile (PT, aPTT, INR), fibrinogen levels, and specific coagulation factor assays. Additional tests to identify underlying conditions such as bleeding disorders or infections.

Treatment Protocols: Hospitalization for close monitoring of maternal and fetal health. Blood transfusions or plasma transfusions to replace lost blood and correct coagulopathy. Administration of medications to control bleeding or improve clotting function. Delivery of the baby if the condition threatens maternal or fetal health, often via cesarean section depending on the severity and gestational age. Management of underlying conditions contributing to coagulation issues. Supportive care such as IV fluids, oxygen therapy, and bed rest as needed.
