What Cm Does Your Water Break?

During active labor, your cervix will dilate from 6 centimeters (cm) to 10 cm. Your contractions will become stronger, closer together and regular. Your legs might cramp, and you might feel nauseated. You might feel your water break — if it hasn't already — and experience increasing pressure in your back.

How dilated do you have to be for your water to break?

If your water (aka “amniotic sac,” “bag of waters” or “membranes”) hasn't broken on its own when you arrive at the hospital, and you're five or more centimeters dilated, your OB might recommend bursting the bag by hand—especially if your cervix seems to be making slow (or no) progress.

Can you be 1cm and your water break?

In most cases, having 1 cm of dilation for a few weeks before delivery will cause no complications. It does not necessarily mean that a woman will go into labor immediately or even the next day. Dilation is just one of many ways that the body prepares for labor. It alone does not mean that labor is imminent.
