how much do you dilate before giving birth?
1821
The cervix must be 100 percent effaced and 10 centimeters dilated before a vaginal delivery. The first stage of labor and birth occurs when you begin to feel regular contractions, which cause the cervix to open (dilate) and soften, shorten and thin (effacement). This allows the baby to move into the birth canal.

The catheter presses against your cervix, encouraging it to dilate open. Once your cervix is dilated to 3 centimeters, the Foley catheter falls out on its own. In some cases, this is enough to start active labor. If not, your doctor might resort to a different method of induction.

During labor, the cervix opens to accommodate the passage of baby's head into the vagina, which is around 10 centimeters (cm) dilated for most term babies.

Dilation is checked during a pelvic exam and measured in centimeters (cm), from 0 cm (no dilation) to 10 cm (fully dilated). Typically, if you're 4 cm dilated, you're in the active stage of labor; if you're fully dilated, you're ready to start pushing.

Stage one is complete when the cervix has dilated to 10 centimeters (cm). Stage two: The body begins pushing out the baby. During this stage, women often feel a strong urge to push.

The active phase. After your cervix dilates to around 3 cm (1 inch), you will enter the active phase of labour, where things really start to get rolling. For the next few hours, your contractions will be strong, painful, and regular. Unlike the early phase, you may no longer be able to talk through these contractions.

You generally start dilating in the ninth month of pregnancy as your due date gets closer. The timing is different in every woman. For some, dilation and effacement is a gradual process that can take weeks or even up to a month. Others can dilate and efface overnight.

But for some, a shorter labour can mean a more intense labour with stronger contractions; while dilation during the first pregnancy happens at roughly 1.2cm per hour, it's more like 1.5cm per hour for second and subsequent births which can make things quicker, but possibly more painful.

The active stage of labor can range from a woman dilating anywhere from 0.5 cm per hour up to 0.7 cm per hour. How fast your cervix dilates will also depend on if it's your first baby or not.

Dilation: Your cervix opens. Typically, if you're 4 cm dilated, you're in the active stage of labor; if you're fully dilated, you're ready to start pushing.

When the opening of the cervix starts to widen, this is called dilation, and it is one sign that labor is approaching. Dilation is typically measured in centimeters (cm). During active labor, the cervix fully dilates to 10 cm.

It begins when your cervix starts to open (dilate) and ends when it is completely open (fully dilated) at 10 centimeters. When the cervix dilates from 0 to 3 or 4 centimeters, contractions get stronger as time progresses.

This part of labor (called the Latent Phase) is best experienced in the comfort of your home. When the cervix dilates from 4 to 8 centimeters (called the Active Phase), contractions get stronger and are about 3 minutes apart, lasting about 45 seconds.

Once you begin active labor, you'll have strong contractions around a minute long and 3-5 minutes apart. It may be hard to talk or move easily. At this point, your cervix will be dilated 3-10 centimeters.

The first stage is the longest part of labor and can last up to 20 hours. It begins when your cervix starts to open (dilate) and ends when it is completely open (fully dilated) at 10 centimeters. When the cervix dilates from 0 to 3 or 4 centimeters, contractions get stronger as time progresses.

The Second Stage of Labor (Delivery) The second stage of labor begins when your cervix is fully dilated at 10 centimeters. This stage continues until your baby passes through the birth canal, vagina, and is born.

The time between dilating to 1 cm and giving birth varies from woman to woman. One woman may go from having a closed cervix to giving birth in a matter of hours, while another is 1–2 cm dilated for days or weeks. Some women do not experience any dilation until they go into active labor.
