You’re 39 weeks pregnant. Every twinge feels like "the one." You’re pacing the living room, wondering if that cramp was a real contraction or just the leftover Thai food from last night. Naturally, the urge to know exactly what’s happening behind the scenes becomes overwhelming. You want to know if you're actually in labor. You want to know if your cervix is doing anything at all.
Basically, you want to know how to check if you’re dilated at home.
It’s a controversial topic. Some doctors will tell you to absolutely never touch your own cervix, while many home-birth advocates and midwives view it as a basic right to know your own body. Honestly, it’s your body. But before you go diving in, there is a lot of nuance to understand about what you’re actually feeling for—and why a "number" might not mean as much as you think it does.
The reality of the "Self-Check"
First off, let’s be real. Checking your own cervix is physically awkward. It’s like trying to touch the back of your throat with your elbow while sitting on a yoga ball. Your cervix is tucked way back, and when you’re heavily pregnant, your belly is, well, in the way.
Medical professionals, like those at the American College of Obstetricians and Gynecologists (ACOG), generally advise against frequent self-checks because of the risk of infection. If your water has broken—even if it’s just a tiny trickle—you should never, ever check yourself. Introducing bacteria into the vaginal canal once the protective amniotic sac is ruptured can lead to chorioamnionitis, which is a serious infection for both you and the baby.
But if your water is intact? It’s generally considered safe as long as your hands are surgical-level clean. Just know that a "fingertip" dilated at home doesn't necessarily mean you’re meeting your baby in two hours. Some women walk around 3 centimeters dilated for three weeks.
How to check if you're dilated at home: The physical process
If you’ve decided to go for it, you need to set the stage. Wash your hands. No, really wash them. Scrub under the nails. Cut your nails short if they’re long—the cervical tissue is incredibly vascular and sensitive; you don’t want to cause a bleed or an abrasion.

Find a position that works. Most women find that squatting or putting one leg up on the toilet or the edge of the bathtub is the only way to reach far enough.
What are you feeling for?
You’re looking for the cervix. It feels sort of like the tip of your nose when it’s closed—firm and rubbery. As it starts to efface (thin out) and dilate, it starts to feel more like your lips, or even the inside of your cheek. It gets soft. It gets "mushy."
- Reach back and up. The cervix isn't usually straight ahead; it’s often angled toward your tailbone (posterior) until labor really gets moving.
- Find the opening. If you’re not dilated, it’ll feel like a small dimple. If you are, you’ll be able to fit a fingertip—or more—into the center.
- Estimate the width. This is the tricky part. Nurses and doctors use their fingers to estimate centimeters. One finger is usually about 1 centimeter. Two fingers side-by-side is roughly 2 to 3 centimeters. If your fingers can stretch apart once inside, you're looking at 4 centimeters or more.
The Purple Line: The weirdest way to check dilation
There is a legendary "old wives' tale" that actually has some scientific backing. It’s called the Purple Line.
In a study published in the journal BMC Pregnancy and Childbirth, researchers looked at whether a reddish or purple line appearing in the intergluteal cleft (the butt crack, to be blunt) could predict dilation. It turns out, for many women, it can.
As the baby’s head descends, it puts pressure on the veins around the sacrum. This can cause a faint line to appear, starting at the anus and moving upward toward the top of the buttocks. The higher the line, the more dilated you might be.
- Bottom of the crack? Early labor.
- Halfway up? Maybe 5-6 centimeters.
- All the way to the top? Get the car keys.
It’s not 100% accurate. In the study, the line appeared in about 76% of women. But hey, it’s non-invasive and doesn’t require a degree in anatomy.

Emotional Signposts: The "Check" without the touch
Honestly, the physical number is often the least important part of the puzzle. Midwives often use "emotional signposts" to tell how far along a person is. This is arguably a much more accurate way of how to check if you’re dilated at home than poking around internally.
Early Labor (0-6 cm)
You’re chatty. You’re excited. You’re probably texting your friends that "this might be it!" You can talk through contractions. You’re still worried about whether the house is clean or if you packed enough snacks.
Active Labor (6-8 cm)
The mood shifts. You stop talking. You might get "the look"—a far-off, glazed expression during contractions. You can no longer talk through the waves. You need to focus. If someone asks you what you want for dinner, you might want to throw a shoe at them.
Transition (8-10 cm)
This is the "I can't do this" phase. You might feel nauseous, start shaking uncontrollably, or get extremely irritable. If you find yourself saying, "I want to go home" (even if you are at home), or "I'm done, call it off," you are likely very close to 10 centimeters.
Why the number can be a liar
The obsession with dilation is real, but it’s also a bit of a trap. We’ve been conditioned to think that labor is a linear 1-to-10 scale, like a loading bar on a computer screen.
It isn't.

You can be 4 centimeters dilated for a week and then stay at 4 centimeters for twelve hours of active labor. Then, you can go from 4 to 10 in twenty minutes. This is why many modern birth experts, like Penny Simkin, emphasize "labor progress" rather than just "dilation." Progress is about the baby’s station (how low they are), the thinning of the cervix, and the intensity of the contractions.
If you check yourself and find you're "only" 2 centimeters after hours of work, it can be devastating. That psychological blow can actually stall labor by triggering adrenaline, which fights against oxytocin (the hormone that drives contractions).
When to stop checking and start moving
If you are trying to figure out how to check if you’re dilated at home because you're trying to time your arrival at a hospital or birth center, look at the 5-1-1 rule instead.
- Contractions are 5 minutes apart.
- They last for 1 minute each.
- This has been happening for 1 hour.
If you hit 5-1-1, the number of centimeters doesn't matter as much as the fact that your body is clearly in a rhythm.
Critical Safety Check
Stop checking yourself and call your provider immediately if:
- You see bright red blood (more than just a "bloody show" mucus).
- You feel something "looping" in the vaginal canal (could be a cord prolapse).
- Your water breaks and the fluid is green or brown (meconium staining).
- You feel a sudden, sharp, constant pain that doesn't go away between contractions.
Actionable Next Steps
Instead of focusing solely on the physical check, use a multi-layered approach to gauge your progress.
- Try the Purple Line method first. It’s easy, safe, and doesn't require internal contact. Have a partner use a flashlight if you can't see it in a mirror.
- Monitor your "Inward Turn." Notice when you stop being able to browse your phone or have a conversation. That is a more reliable indicator of active labor than a self-cervical check.
- Keep it clean. If you must perform an internal check, use sterile gloves or wash your hands like you're about to perform surgery. Avoid checking more than once every few hours.
- Trust the 5-1-1 rule. Use a contraction timer app. When the frequency and intensity are consistent, your body is doing the work regardless of what your fingers tell you.
- Focus on the station. If you do check, notice how low the baby’s head feels. If it feels like it’s right there, pressing against your fingers, things are moving, even if the "opening" feels small.
Ultimately, your cervix is not a crystal ball. It’s a muscle that’s doing a very difficult job. Whether you’re 2 centimeters or 8, the best thing you can do is stay hydrated, stay mobile, and keep your stress levels as low as possible.
