Main Causes of Black Vaginal Discharge

Implantation Bleeding

If the black vaginal discharge is continuous and the menstrual period is delayed, such secretions could appear due to the implantation process. Dark brown or even black color discharge can occur 6 to 12 days after egg fertilization. The newly-formed embryo begins its attachment to the uterine wall. The uterine lining is rich in blood and regularly sheds once in a month, if fertilization does not occur. If conception is successful, some blood vessels can be ruptured by the embryo in the process of its implanting. Discharge during the egg-attachment is rather a common symptom. It appears in 30% of all pregnancies and is called implantation bleeding. Moreover, its color can also vary: it can be brown, black or pink. This factor depends on how old the blood from the uterine lining is, i.e. how much time it took for this blood to pass out of the body.

To diagnose implantation bleeding you need to contact your doctor and pass several tests. Remember, that the home pregnancy test (HPT) will be positive and accurate only if your hCG level is enough to be detected in the urine. If implantation has occurred and your test is negative, in some time other pregnancy signs will appear. Anyway, if you suspect conception and experience black vaginal discharge, try to discuss this matter with your ob-gyn. Cervical mucus with black drops of blood is the first symptom of the premature placental abruption. Dark secretions during pregnancy can also indicate a miscarriage or an ectopic pregnancy. In such a case a woman can feel lightheadedness and palpitation.
