Bloody show is the passage of a small amount of blood or blood-tinged mucus through the
vagina near the end of
pregnancy. It can occur just before
labor or in early labor as the
cervix changes shape, freeing mucus and blood that occupied the cervical glands or cervical os. Bloody show is a relatively common feature of pregnancy, and it does not signify increased risk to the mother or baby. A larger amount of bleeding, however, may signify a more dangerous, abnormal complication of pregnancy, such as
placental abruption or
placenta previa. Large amounts of bleeding during or after childbirth itself may come from uterine
atony or
laceration of the cervix, vagina, or
perineum.
