If you’ve ever been in labour (or even just googled anything about birth ), you’ve probably heard the phrase: “You’re X centimetres dilated.” And if you’re anything like most people, you immediately start doing the math in your head, trying to predict exactly when your baby will arrive.
But here’s the truth: vaginal exams (VEs) are not a crystal ball.
Dilation Is Not a Progress Bar
We love the idea that birth is a straight road from 0 to 10cm, with each centimeter meaning you’re one step closer to baby-in-arms. & this theory is based on some pretty outdated research (we’re talking 1950’s ladies) on pretty small population, and assumes that women’s bodies all follow the same mathematical trends in order to birth a baby. At it’s time it was considered a gold standard tool, but in reality doesn’t consider a variety of influences, or the individual labouring woman.
But the reality? Labour just isn’t that predictable!
✨ Some people stay at 3cm for days and then have a baby in an hour.
✨ Others sit at 9cm for hours with no baby in sight.
✨ And some go from “not in labor” to “baby is here” in the blink of an eye.
Your cervix is not an egg timer. It doesn’t tell us how long you have left or when your baby will arrive. It’s just one tiny piece of a much bigger picture & whilst it can be useful to help us understand some elements of your labour, it isn’t not a definitive resource that accurately predicts.
What Actually Matters in Labour
Instead of obsessing over dilation & measurable statistics, let’s look at the REAL signs of labor progress:
✅ Contraction Patterns: Are they getting longer, stronger, and closer together?
✅ Baby’s Position: A well-positioned baby (head down, facing your back) makes labour smoother (biomechanics through pregnancy can help with this!)
✅ Hormonal Shifts: Your body is brewing the perfect mix of oxytocin, endorphins, and adrenaline to move things along.
✅ Your Mindset & Movement: Fear and tension can slow labour down, while movement, breathing, and relaxation help things along.
So, Should You Even Get a Vaginal Exam?
Vaginal exams can be useful in certain situations. They can tell us things like:
- If your cervix is softening and thinning out (effacement matters just as much as dilation!).
- Baby’s position and station (how low they are in your pelvis).
- & they might just be the thing you need to help you carry on doing what you’ve been doing.
But here’s the key: You don’t HAVE to have one.
If you find them uncomfortable, stressful, or unhelpful, you can decline. Your body is still doing what it needs to do, whether or not someone checks how many centimeters your cervix has opened.
Bailey’s Final Thoughts
Next time someone tells you their story of “I was only X cm,” & it took “X amount of time” just smile, nod, and remember—your body knows what it’s doing, even if the numbers don’t tell the full story.
Birth is not a math equation. Trust your body. Trust the process. And don’t let a single number define your experience.
