The cervix at 39 weeks pregnant softens, thins, and may dilate as the body prepares for labor.
Understanding Cervical Changes at 39 Weeks Pregnant
At 39 weeks pregnant, the cervix undergoes significant changes signaling that labor is near. The cervix, a cylindrical passage connecting the uterus to the vagina, plays a vital role during childbirth. Throughout pregnancy, it remains firm and closed to protect the baby inside the uterus. However, as you approach full term, especially around 39 weeks, it begins to soften (a process called ripening), thin out (effacement), and sometimes dilate (open) in preparation for delivery.
These changes don’t happen overnight but develop gradually. The timing and extent of cervical changes vary widely among women. Some may experience early softening and dilation weeks before labor begins, while others might show minimal cervical change until contractions start. Understanding what happens to your cervix at this stage can help you recognize signs of impending labor and communicate effectively with your healthcare provider.
The Role of Cervical Ripening
Cervical ripening is essential for a smooth labor process. Before labor starts, the cervix transitions from a hard, closed state to a soft, pliable one. This softening results from biochemical changes in cervical tissue—collagen fibers break down, water content increases, and the cervix becomes more elastic.
This process allows the cervix to dilate easily during contractions. At 39 weeks pregnant, many women will notice their cervix becoming softer when examined by their obstetrician or midwife. This change often precedes other labor signs like regular contractions or water breaking.
Effacement and Dilation: What to Expect
Two key factors doctors monitor are effacement and dilation:
- Effacement: This refers to how much the cervix has thinned out or shortened. It’s measured in percentages from 0% (no thinning) to 100% (completely thinned). At 39 weeks pregnant, effacement may range widely but often reaches between 50% and 80% as the body prepares for labor.
- Dilation: This measures how open the cervix is in centimeters from 0 cm (closed) to 10 cm (fully dilated). Some women might have no dilation at all at 39 weeks; others might be dilated up to 3 or even 4 centimeters if early labor has begun.
It’s important to note that cervical dilation does not always correlate with when labor will start. Some women remain dilated for days or weeks before active labor kicks in.
Cervical Position and Consistency Changes
Alongside effacement and dilation, the cervix’s position and texture shift:
- Position: The cervix moves from a posterior (toward the back) position to an anterior (toward the front) one as labor approaches.
- Consistency: It becomes softer—sometimes described as feeling like your lips rather than your nose.
These subtle changes can be detected during pelvic exams by healthcare providers but are difficult for most women to assess on their own.
The Significance of “39 Weeks Pregnant Cervix” Status
Knowing your cervical status at this stage helps predict how close you are to delivery but isn’t a guarantee of exact timing. For example:
- A soft, effaced cervix with some dilation suggests that labor could start soon—possibly within days.
- A firm, closed cervix means that despite being full term, your body is not yet ready for active labor.
Doctors sometimes use cervical exams combined with other assessments such as fetal position and contraction patterns to make decisions about inducing labor or continuing expectant management.
Cervical Exams: What Happens During Checkups?
During prenatal visits at or after 39 weeks, your healthcare provider may perform vaginal exams to assess your cervix:
- Your provider will insert two gloved fingers gently into your vagina reaching toward the cervix.
- They will feel for softness, length (effacement), dilation size in centimeters, position relative to vaginal canal orientation, and consistency.
- This exam provides valuable information about your readiness for labor but can be uncomfortable or cause slight spotting due to increased sensitivity of ripened tissue.
Many women find these exams nerve-wracking but understanding what’s happening can ease anxiety.
Table: Typical Cervical Changes Near Full Term (Weeks 37-40)
| Gestational Week | Effacement (%) | Dilation (cm) |
|---|---|---|
| 37 Weeks | 0-30% | 0-1 cm |
| 38 Weeks | 20-50% | 0-2 cm |
| 39 Weeks | 50-80% | 0-4 cm |
| 40 Weeks+ | 80-100% | 4-10 cm (active labor) |
This table demonstrates typical ranges but remember individual experiences vary widely.
Cervical Mucus Changes at 39 Weeks Pregnant Cervix Stage
Another sign of cervical readiness involves changes in cervical mucus or discharge:
- Mucus Plug Loss: As the cervix softens and opens slightly, you might notice discharge mixed with blood called “bloody show.” This mucus plug seals the uterus during pregnancy protecting against infection.
- This loss signals that your body is preparing for delivery but doesn’t necessarily mean immediate labor—it can happen days before contractions begin.
- The mucus tends to become thinner and more watery as well when nearing birth.
Tracking these changes alongside cervical exams offers a fuller picture of what’s happening internally.
Pain or Discomfort Related to Cervical Changes at Full Term
Some women experience sensations linked directly to their changing cervix:
- Pelvic pressure: As the baby descends lower into the pelvis near term, pressure on an already softened cervix can cause discomfort or aching sensations.
- Mild cramping: Light menstrual-like cramps may occur due to stretching of cervical tissues.
- Sensation during intercourse: Increased sensitivity or spotting after sex can occur because of a delicate ripened cervix.
These symptoms vary greatly; some women feel nothing unusual until active contractions begin.
The Impact of Cervical Status on Labor Induction Decisions
At 39 weeks pregnant, if there’s concern about health risks like preeclampsia or diabetes—or if pregnancy extends beyond due date—doctors evaluate cervical status before recommending induction.
The Bishop Score is a common tool used here; it grades five factors including dilation, effacement, consistency, position of the cervix, and fetal station. A higher score means induction is more likely to succeed naturally because the cervix is favorable.
If your “39 Weeks Pregnant Cervix” exam shows low effacement and no dilation despite medical need for delivery soon, providers may use medications like prostaglandins or mechanical methods such as Foley catheters to help ripen your cervix before inducing contractions.
Caring for Your Body While Monitoring Cervical Changes
Being mindful of your body’s signals while awaiting labor can help you stay comfortable:
- Avoid excessive vaginal exams: Frequent checks aren’t necessary unless medically indicated since they may increase infection risk once membranes rupture.
- Pace yourself physically: Rest when tired but keep light activity; gentle walking encourages baby’s descent.
- Nourish well: Balanced meals support energy reserves needed for birth.
- Mental preparation: Understanding cervical changes helps reduce anxiety about unknown sensations during late pregnancy.
Staying informed empowers you through this final stretch.
The Final Countdown: What Happens After Your Cervix Reaches Full Ripeness?
Once your cervix reaches full effacement (100%) and dilates fully (10 cm), active labor begins—a phase marked by strong regular contractions pushing your baby through the birth canal.
Before this point though:
- You might experience irregular Braxton Hicks contractions which do not cause significant cervical change but help prepare uterine muscles.
Once true labor starts:
- Your contractions grow longer-lasting and closer together while your cervix continues opening rapidly.
This progression culminates in delivery within hours typically after full dilation is reached.

Frequently Asked Questions
What cervical changes occur at 39 weeks pregnant cervix?
At 39 weeks pregnant, the cervix softens, thins (effaces), and may begin to dilate. These changes prepare the body for labor by making the cervix more elastic and ready to open during contractions. The timing and degree of these changes vary widely among women.
How does cervical ripening affect the 39 weeks pregnant cervix?
Cervical ripening at 39 weeks involves biochemical changes that soften and increase the elasticity of the cervix. This process breaks down collagen fibers and increases water content, allowing the cervix to dilate more easily when labor begins.
What is effacement in a 39 weeks pregnant cervix?
Effacement refers to the thinning or shortening of the cervix as it prepares for labor. At 39 weeks pregnant, effacement can range from 50% to 80%, indicating that the cervix is becoming thinner and ready to open for delivery.
Can a 39 weeks pregnant cervix be dilated without labor starting?
Yes, some women may have a cervix dilated up to 3 or 4 centimeters at 39 weeks without active labor beginning. Cervical dilation does not always predict when labor will start, as some remain dilated for days or weeks before contractions begin.
How can understanding the 39 weeks pregnant cervix help expectant mothers?
Knowing how the cervix changes at 39 weeks helps expectant mothers recognize signs of impending labor. It also enables better communication with healthcare providers about cervical status and what to expect as delivery approaches.
