Bleeding after 20 weeks of gestation — ‘Bloody show’ is the term used to describe the small amount of blood with mucus discharge that may precede the onset of labor by as much as 72 hours. The term antepartum bleeding typically refers to uterine bleeding after 20 weeks of gestation that is unrelated to labor and delivery. Antepartum bleeding complicates 4 to 5 percent of pregnancies. The major causes are:

●Placenta previa (20 percent)

●Abruptio placenta (30 percent)

●Uterine rupture (rare)
