As you enter your third trimester, it might feel like your pregnancy is stretching on forever. While that may not be the case, the final weeks can seem excruciatingly long. However, as you prepare for the arrival of your little one, your body is also gearing up for labor and delivery. This is where cervical effacement, along with dilation, comes into play.
You may already be aware of certain signs that indicate labor is near, such as Braxton Hicks contractions and increased trips to the bathroom. However, effacement might be a bit more elusive since it’s not something you can directly observe or feel. Let’s break down what effacement means, how it’s measured, and more.
What is Cervical Effacement?
Here’s a quick refresher on anatomy! The cervix is the narrow, lower end of the uterus that connects to the vagina. It acts as the barrier between your baby and the outside world. Typically, the cervix is firm and closed, measuring around 3.5 to 4 centimeters. As labor begins and contractions start, the cervix thins, softens, and shortens—a process known as effacement, according to health experts.
Understanding Effacement Percentages
Effacement is expressed in percentages. When you reach 100 percent, your cervix has thinned enough for childbirth. For instance, if your healthcare provider tells you that you’re “70 percent effaced,” it means you’re nearly three-quarters ready for delivery. If you’re 80 percent effaced, then you’re just a bit more than three-quarters of the way there!
Effacement vs. Dilation
You may notice that discussions about effacement often accompany talks about dilation. This is because both processes work in tandem to prepare your cervix for the baby’s passage. While effacement is measured in percentages up to 100, dilation is measured in centimeters, ranging from zero to 10. When you reach 100 percent effaced and are dilated to 10 centimeters, it’s time for your little one to make their entrance!
Signs of Cervical Dilation
If your cervix is effacing, dilation usually follows soon after. It’s crucial to be attuned to your body during this period. Recognizing the signs of dilation will help ensure you’re prepared for labor, whether you’re planning a home birth or heading to the hospital.
- Lightning Crotch: This term refers to sharp pain in the vaginal area, often caused by the baby’s head pressing against nerves as it moves lower into the pelvis.
- Back Pain and Cramping: While aches are common during pregnancy, cramping focused just above the pubic bone can signal the onset of labor.
What Does Effacement Feel Like?
While you typically won’t “feel” effacement itself, some women report experiencing irregular contractions that are stronger than Braxton Hicks but not as intense as actual labor contractions. Signs of effacement may include:
- Loss of Mucus Plug: Throughout your pregnancy, your cervix is sealed by a mucus plug. As labor approaches and the cervix effaces, this plug may dislodge, leading to what’s known as the “show.” If it has a tinge of blood, it’s referred to as a “bloody show.”
- Increased Discharge: As your cervix thins, you’ll likely notice an uptick in vaginal discharge.
- The “Drop”: As the cervix effaces, the baby may lower into the pelvis. You may feel more pressure and discomfort in your pelvic area.
How Long After Effacement Does Labor Start?
There’s no one-size-fits-all timeline since every pregnancy is unique. However, beginning in your ninth month, your healthcare provider will start monitoring your cervix for effacement. Although some women may choose to check their own cervix, it’s generally advisable to leave this to a professional.
Can You Speed Up Effacement?
If you want to encourage effacement, it’s essential to consult your healthcare provider before attempting any methods to expedite the process. Some popular suggestions include:
- Aligning Your Feet: Keeping your toes parallel may help open up the pelvis.
- Using a Birthing Ball: Sitting and moving on a birthing ball can aid in opening the pelvis.
- Intimacy: Engaging in sexual activity can help soften the cervix due to prostaglandins in semen. Additionally, orgasms can stimulate uterine contractions.
- Relaxation Techniques: Managing stress can facilitate dilation. Surround yourself with loved ones and engage in activities that make you laugh.
- Nipple Stimulation: This can help release oxytocin, which may initiate contractions, but consult your doctor if you have a high-risk pregnancy.
- Castor Oil: Consuming a small amount can stimulate the release of prostaglandins, helping with effacement.
- Massages: A deep tissue massage can elevate oxytocin levels, potentially initiating labor contractions with your doctor’s approval.
- Evening Primrose Oil: Known to activate prostaglandins, it may assist in softening the cervix.
Sometimes, even if your cervix hasn’t fully effaced, your healthcare provider may choose to induce labor for the safety of you and your baby.

Summary
Cervical effacement is a critical part of the labor process, indicating that your body is preparing for delivery. Understanding how effacement and dilation work together will help you recognize signs and symptoms leading up to childbirth. While there’s no guaranteed timeline for when labor will start after effacement, being aware of these changes can help you stay prepared.
