Active labor and VBAC

Women who plan a vaginal birth after cesarean (VBAC) are instructed to go to the hospital early in active labor.

Active labor can last 2 to 3 hours (or much longer), during which time your cervix dilates from 3 cm (1.2 in.) to 10 cm (3.9 in.). Further thinning (effacing) of the cervix occurs during this phase. Contractions are more frequent and stronger and cause increasing discomfort.
