Black discharge and back pain in early pregnancy may be caused by ectopic pregnancy, preeclampsia and embryonic abruption.
1. Ectopic pregnancy: when the fertilized egg is deposited outside the uterus, as the embryo grows, it will cause bleeding manifested as brown discharge, and there will also be back pain and other manifestations, and if it ruptures, there will be severe abdominal pain.
2. Pre-eclampsia: When the embryo develops abnormally or the embryo is stimulated by the environment, pre-eclampsia may occur, resulting in backache, abdominal pain, vaginal bleeding, and when the bleeding is less, it is brown discharge.
3. Embryonic arrest: when the embryo dies in the uterus, it may also trigger vaginal bleeding and brown discharge, and the dead embryonic tissues may irritate the uterus, causing backache and abdominal pain.
Women who find brown discharge in early pregnancy may also have other causes, it is recommended to consult a doctor when symptoms occur, complete the relevant examinations under the guidance of the doctor, to clarify the cause of the disease, and give targeted treatment.
