Brown discharge at 38 weeks of pregnancy may be redness, but it may also be caused by other reasons, such as placenta previa, placental abruption or cervical polyps.
Redness refers to a small amount of bleeding caused by the separation of the fetal membranes from the uterine wall near the endocervical os, allowing localized capillary rupture, which may manifest itself as a brownish discharge when the blood mixes with the mucus plug of the cervical canal. If there are other symptoms, such as irregular or regular contractions and the head of the fetus falling, it is possible to see red, which is a premonitory labor.
However, if the pregnant woman is combined with placenta praevia or cervical polyps, it may also lead to bleeding in late pregnancy, usually without abdominal pain; if there is a brown discharge accompanied by abdominal pain, you need to be alert to the possibility of placental abruption. These cases are not redness, belong to the abnormal pregnancy bleeding, need to consult a doctor in time.
