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.
There are 3 signs of the onset of labor:
- A bloody show
- Rupture of membranes (Waters breaking)
- Onset of tightenings or contractions
However, these may occur at any time and in any order. Some women neither experience a bloody show nor have their waters break until well into advanced labor.
