It is normal to have brown nightmare but no other discomfort. The color of the nightmare will change with the prolongation of the postpartum period. The nightmare will be dark red within a week after delivery, and after more than a week it will become brown or yellow, and at the end of the period it will be white, which is the normal evolution of the nightmare and does not require special treatment. However, the brownish color of the dew may be accompanied by itching of the vulva, abdominal pain and fever, which may be abnormal and may be caused by intrauterine infection. Due to prolonged retention of postpartum dew in the uterus, lack of attention to vulva hygiene and premature intercourse can cause intrauterine infection, resulting in brown dew. If there is intrauterine infection, you need to take anti-inflammatory drugs such as amoxicillin and metronidazole, and you also need to take motherwort to promote the discharge of malodex.
