Bleeding during labor
Beside placenta previa and placental abruption, uterine rupture can occur as a very serious condition leading to internal or external bleeding. Bleeding from the fetus is rare, usually not heavy, but always very serious for the baby.
After delivery (Postpartum)
Trauma from the delivery may tear tissue and vessels leading to significant postpartum bleeding. Uterine atony refers to the inability of the uterus to contract and will lead to continuous bleeding. Retained placental tissue and infection may contribute to uterine atony.
