Vaginal birth - series—Procedure, part 2

Procedure, part 2

Overview

Contractions happen when your uterine muscles involuntarily tighten and relax. When true labor begins, you feel contractions at regular intervals. As labor progresses, these contractions get longer, stronger, and closer together. During active labor, you may feel intense pain or pressure in your back or abdomen during each contraction. You may also feel the urge to push or bear down, though your doctor will ask you to wait until your cervix is completely dilated.
