What Actually Happens During Labour (From 1cm to Baby Out)
If you’re a first-time mum heading towards labour, chances are you’ve Googled things like “what does labour actually feel like”, “how painful is 5cm”, or “will I know when it’s time?” — probably at an ungodly hour.
Movies make labour look dramatic. Social media makes it look empowering. Your auntie makes it sound traumatic.
If you’re the kind of first-time mum who wishes someone had explained all this before you started Googling contractions at 2am, you might also relate to what I wish I knew before pregnancy, especially the parts no one casually mentions.
So let’s talk about what actually happens during labour — from 1cm dilated to baby out — without fear-mongering, and without pretending it’s all candles and calm breathing.
Labour, Explained in Plain English
Labour is basically your uterus doing a very intense, very organised workout to help your baby exit the building.
Doctors and midwives usually divide labour into three stages:
- Early & active labour (dilation from 1cm to 10cm)
- Pushing (baby coming out)
- Afterbirth (placenta delivery)
But for first-time mums, it helps to break that down even further — because 1cm labour and 9cm labour are NOT the same experience.
Let’s go step by step.
1–2cm: Early Labour (The “Is This Even Labour?” Phase)
This stage can last hours… or days. Yes, days. And that’s normal.
What’s happening in your body
- Cervix starts thinning (effacing) and opening
- Contractions may be irregular and mild
- Your body is basically warming up
What it feels like
- Period cramps
- Dull lower back ache
- Tightening across your belly
- “Something feels off, but I’m not sure what”
Many women spend this phase cleaning their house, bouncing on a yoga ball, or googling every symptom.
This part of labour surprises a lot of first-time mums, which is why it’s one of the things I included in the things no one really talks about before giving birth.
3–4cm: Labour Is Officially a Thing Now
Congratulations. You’re technically in labour.
What changes here
- Contractions become more regular
- Cervix is opening steadily
- You might start timing contractions “just in case”
What contractions feel like
- Stronger menstrual cramps
- Tightening that comes in waves
- You can still talk through them (but maybe with attitude)
Most hospitals won’t admit first-time mums until around 4–5cm, which is why many women get sent home if they go in too early.
5–6cm: Active Labour (Things Get Real)
This is where labour usually shifts gears.
What’s happening
- Cervix dilates faster
- Contractions are closer together
- Your body is very focused on the task
What it feels like
- Strong, deep cramping
- Pressure in the pelvis
- Talking through contractions becomes difficult
- You may start doubting your life choices
Many women describe this phase as intense but manageable — especially with breathing, movement, or pain relief.
This is also when some mums opt for pain relief options like gas or an epidural (depending on availability and hospital policy).
7–8cm: Transition (AKA “I Cannot Do This”)
Welcome to transition — often the shortest but hardest part of labour.
What’s happening
- Cervix is almost fully dilated
- Baby is moving lower
- Hormones are going wild
What it feels like
- Very strong, very frequent contractions
- Nausea, shaking, sweating
- Feeling overwhelmed or panicky
- Saying things like “I can’t do this anymore”
Here’s the thing no one tells you: feeling like you can’t cope often means you’re very close.
Midwives actually see this as a sign labour is progressing well.
9–10cm: Fully Dilated (Almost There)
At 10cm, your cervix is fully open — but pushing doesn’t always start immediately.
What happens next
- Baby rotates into position
- You may feel pressure rather than pain
- Some providers encourage “labouring down” before pushing
What it feels like
- Intense pressure in your bottom
- A strong urge to push (or not yet — both are normal)
- Contractions may feel different now
This stage can be surprisingly quiet compared to transition.
The Pushing Stage: Baby Out
This is the part everyone asks about — and also the part that’s wildly different for every woman.
How long pushing takes
- First-time mums: anywhere from 20 minutes to 2+ hours
- Depends on baby’s position, epidural use, and fatigue
What pushing feels like
- Strong pressure
- Relief when pushing during contractions
- Stretching and burning sensation as baby crowns
Despite how it sounds, many women say pushing feels productive, not just painful.
You’re no longer waiting — you’re doing.
Crowning: The “Ring of Fire” (Let’s Be Honest)
Crowning is when baby’s head stretches the vaginal opening.
What to expect
- Intense burning or stretching
- Very short-lived sensation
- Baby is literally right there
Midwives may guide your pushing here to reduce tearing.
The perineum is the area of skin and muscle between your vaginal opening and anus. During birth, it stretches a lot — often more than you’d ever imagine possible.
Will I tear?
- Many first-time mums experience some degree of tearing
- Most tears are minor (1st or 2nd degree) and heal well
- Severe tears (3rd or 4th degree) are much less common
Between Crowning and Baby Out: The Stretching Phase (No One Explains This Properly)
Crowning doesn’t mean baby pops out in one dramatic push (sorry, movies).
There’s usually a pause-and-stretch phase where your body does something surprisingly clever.
What’s actually happening
- Baby’s head stays visible at the vaginal opening
- The perineum (skin between vagina and anus) stretches slowly
- Tissues are thinning and making space rather than tearing instantly
Midwives often encourage short, gentle pushes or panting here instead of full-force pushing — and this is very intentional.
Head Out, Pause Again (Yes, There’s Another Pause)
Once baby’s head is born, there’s often another brief pause.
Why this pause matters
- Baby rotates naturally so the shoulders fit
- Your body adjusts to the next stretch
- Care provider checks for the umbilical cord around the neck
This is normal and not an emergency.
Shoulders, Then the Rest of the Body
After the head:
- One shoulder comes out
- Then the second
- The rest of the body usually slides out smoothly
This part often feels less intense than the head and perineal stretch.
And just like that — baby is out.
Baby Is Out: The First Few Minutes
Once baby is born:
- Baby is placed on your chest (skin-to-skin)
- Cord may be delayed before clamping
- Baby is checked quickly if needed
This moment often feels surreal. Time gets weird. Pain fades into the background.
Afterbirth: Delivering the Placenta
Yes, there’s still one more thing.
What happens
- Mild contractions
- Placenta usually comes out within 5–30 minutes
- Often feels like a gentle push compared to labour
If stitches are needed, they’re done after this stage.
Common Labour Questions First-Time Mums Ask
Will my water break dramatically?
Sometimes. Other times it’s a slow leak. Some women’s water doesn’t break until pushing.
How long does labour last?
For first-time mums, 8–18 hours is common — but there’s a huge normal range.
Will I know when it’s time?
Usually, yes. When contractions stop being ignorable, you’re probably there.
What Doctors & Midwives Base Decisions On
Medical teams look at:
- Cervical dilation
- Effacement
- Baby’s station (how low baby is)
- Contraction pattern
Guidelines from organisations like the World Health Organization (WHO) and American College of Obstetricians and Gynecologists (ACOG) support allowing labour to progress at its own pace when mum and baby are well.
Labour isn’t one long scream-fest — it’s a series of stages, each with its own rhythm. Before labour reaches this stage, many women experience early signs that are easy to misread. You can read more about how to tell if labour is actually starting.
Knowing what’s happening at each centimetre doesn’t make labour painless, but it does make it less scary. And for many first-time mums, that alone makes a huge difference.
If you want to keep learning, start with understanding when labour is really starting and when it’s time to head to the hospital — those two things cause the most unnecessary stress.
