Vaginal birth - series—Indications

Indications - Body Changes Before Labor 2

Overview

Your body makes some amazing changes in the days and hours leading up to your baby's birth.

A day or two before labor begins, the mucus plug that sealed off your uterus detaches from the cervix and passes through your vagina. This discharge is sometimes called "bloody show" because it's tinged with blood.

Before labor begins or in the early stages of labor, your amniotic sac may rupture and you may feel fluid trickle or gush out of your vagina. If your "bag of waters" doesn't break on its own, your doctor may rupture it manually.
