37 weeks +2 brown discharge may be a reaction to labor, suggesting that the birth is imminent, but also may be caused by placental abruption, placenta praevia and other causes.
1. Prolonged labor reaction: 37 weeks +2 vaginal small amount of brown discharge, may be the red, is a sign of prolonged labor, suggesting that the birth is imminent. When labor is approaching in late pregnancy, the fetal membranes near the cervical os may be slightly detached from the uterine os and capillaries rupture, resulting in a small amount of vaginal bleeding.
2. Placental abruption: If the brown discharge is caused by placental abruption, the labor is not imminent. Rather, it is because there is a peeling surface between the placenta and the wall of the uterus, and there is an accumulation of blood on the peeling surface, which will form a blood clot, and therefore a brown discharge will appear in the vagina at 37 weeks + 2.
3. Placenta praevia: generally refers to after 28 weeks, the placenta position is lower than the fetal prelude, attached to the lower end of the uterus, the lower edge of the uterus reaches or covers the cervical opening, and is not a sign of fast birth. The main manifestation is a sudden unprovoked, painless vaginal bleeding in late pregnancy or at the time of labor, hence the appearance of brown discharge at 37 weeks + 2.
If the patient 37 weeks + 2 brown discharge, it is recommended to go to the hospital in time to identify the cause of the disease, and actively cooperate with the doctor for treatment.
