Here's a play by play of what happens when.
Duration: An average of 12 hours
What happens: During this stage, your cervix dilates. Early on, contractions may be mild, but become more intense and closer together during active labor. During early or active labor, your water may break and you may have vaginal bleeding. When your cervix is 8 to 10 centimeters dilated, birth is imminent and contractions can be particularly intense lasting a minute or so.
Duration: Two hours or longer.
When the cervix is 10 centimeters dilated and fully
effaced, you're ready to push your baby out. For more efficient
pushing, take advantage of gravity. Raise the bed into a chair
position so you're semi-squatting. Or try squatting on the
or floor while holding onto
your partner and labor coach for support.
Duration: Up to 30 minutes
You're not done yet. During this stage, contractions will continue until the placenta is delivered, but they'll be much less painful.
