Brown discharge at 38 weeks of pregnancy may be caused by labor, placenta praevia, vaginitis and other reasons.
1. Prolonged labor: 38 weeks is already full-term and may be delivered at any time, usually 24 to 48 hours before delivery, the cervical opening begins to dilate. At this time, the fetal membranes near the cervical opening separate from the uterine wall, and blood vessels will rupture, resulting in a small amount of bleeding to the point of brown discharge at 38 weeks of pregnancy.
2. Placenta praevia: Placenta praevia means that the lower edge of the placental tissue reaches the endocervical os and attaches to the lower part of the uterus, which can cause vaginal bleeding in late pregnancy and is usually not accompanied by abdominal pain.
3. Vaginitis: During pregnancy, the higher level of female hormones can lead to vaginal inflammation due to the imbalance of the flora in the vagina. When vaginal inflammation is severe, it will lead to vaginal mucosal congestion and edema, which will result in a small amount of vaginal bleeding or brown discharge at 38 weeks of pregnancy.
Brown discharge at 38 weeks of pregnancy may be caused by a variety of reasons, it is recommended to go to the hospital for timely examination to clarify the cause of the disease and then give targeted treatment under the guidance of the doctor.
