During latent labor, your cervix will dilate about three centimeters, a process that results in mild, brief contractions, which are spaced five to twenty minutes apart. Your amniotic sac MAY rupture now, but it's more likely that your water will break once you're in the hospital. Expect to notice discharge, known as the bloody show, and to experience back aches and cramping. At the end of latent labor, the active labor phase begins and you'll head to the hospital.
