Cervical Effacement: What You Need to Know
It all comes down to dilation and effacement, which is the opening or opening of the cervix to allow the baby’s head and body to pass through.
What is Effacement?
The cervix is the gateway between the uterus and the vaginal canal, and it needs to soften, thin (efface), and dilate (open) in order for the baby to enter the birth canal.
Dilation and Effacement: What’s the Difference?
Your cervix will begin to efface as your baby’s head presses down on it, going from completely closed (0 centimeters) to about 3 centimeters, and you’ll be fully dilated and ready for the pushing stage of labor at 10 centimeters.
Cervical Effacement Symptoms
Cervical effacement occurs when the baby’s head presses against the cervix. Braxton Hicks contractions and labor contractions are thought to contribute to effacement, as is the loss of the mucus plug or bloody show.
How to Check Cervix Dilation and Effacement
It’s possible to check your own cervix for dilation and effacement; it’s common for a cervix to begin effacement before it begins to dilate. Some women try to induce labor by walking, squatting, or having sex.
Dilation and Effacement Chart
You’ll be on your way to meeting your baby once your cervix is effaced and dilated, as shown in the chart below.
How do you know if you are dilating?
Dilation: Your cervix opens and is measured in centimeters (cm) during a pelvic exam, ranging from 0 cm (no dilation) to 10 cm (fully dilated). 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.
Can you feel dilation or effacement?
As labor progresses, your cervix softens, shortens, and thins ( effacement ), causing you to have uncomfortable but non-painful contractions or no contractions at all. Effacement is often expressed in percentages; at 0% effacement, the cervix is at least 2 centimeters (cm) long, or very thick.
Is cervix dilation painful?
The pain experienced during dilation is similar to that experienced during menstruation (though much more intense), as period pains are thought to be caused by endometrium passing through the cervix, whereas the majority of the pain experienced during labor is caused by the uterus contracting to dilate the cervix.
Do you think before you dilate?
Most effacement occurs in the early stages of labor, when your cervix is dilating from 0 to 6 centimeters, and the opposite may be true if you’ve already had one or more babies.
How can you tell your going into labor soon?

What week do you start dilating?
Then, a few days to 24 hours before delivery day, you’ll notice bloody show as the capillaries in your cervix begin to rupture, tinting the vaginal mucus pink or streaking it with blood.
When do doctors start checking for dilation?
Your cervix’s dilation and effacement might be checked every week starting at week 36 (or earlier! ), or not until week 38 or 39, or your OB might not do a vaginal exam until you’re in labor, depending on the doctor and the practice.
How can I speed up labor at 3 cm dilated?

How many cm dilated is too late for an epidural?
When possible, health care providers should wait to administer epidurals until the cervix has dilated to 4 or 5 centimeters, according to the American College of Obstetricians and Gynecologists, or ACOG.
What dilation do they admit you?
Your doctor or midwife will tell you to go to the hospital for active labor, which lasts three to five hours and lasts from the time your cervix is 3 cm to the time it is dilated to 7 cm. True labor produces signs you don’t want to ignore.
What does 1cm dilated mean?
Your cervix will begin to open ( dilate ) and thin out ( efface ) during the first stage of labor to allow your baby to move through your birth canal. Dilation can range from 1 centimeter (less than 1/2 inch) to 10 centimeters before there is enough room to push your baby into the world.
Can you be in labor and not know it?
It’s unlikely that you’ll go into labor without warning; instead, your body will alert you that the big day is approaching, so you can prepare your hospital bag and be ready to go to the hospital when the time comes.
How dilated should I be at 38 weeks?
You’ll have strong contractions that last about a minute and are spaced 3-5 minutes apart, making it difficult to talk or move around, and your cervix will be dilated 3-10 centimeters. (Dilating 1 cm/hr is textbook, but it’s different for every woman.)
How long can you stay at 4 cm dilated?
What to expect: Early labor will last 8-12 hours, and your cervix will efface and dilate to 4 centimeters. Contractions will last 30-45 seconds, with 5-30 minutes of rest in between.
