How labor unfolds

The stages of labor, start to finish

A plain-language timeline of the stages of labor — early and active contractions in the first stage, the pushing and birth of the second stage, and delivering the placenta in the third. See roughly what happens in each stage, why every labor's timing is different, and when it's time to go in. Educational only, and never a replacement for the plan your provider gave you.

The stages are the same for everyone; the timing is not. This is a map of the journey — your provider's plan is the one to follow.

Stages of labor timeline

The timeline

Explore each stage of labor

Labor moves through three stages, and the first stage has two phases. Select a stage to see roughly what happens, how it may feel, and how long it tends to take — remembering that every labor's timing is different.

First stage · Early (latent) labor

Contractions begin and the cervix starts to open

What's happening

Labor begins. Mild, often irregular contractions start the slow work of softening, thinning (effacing), and opening (dilating) the cervix — up to about 6 cm by the end of this phase. A “bloody show” (pink or blood-tinged mucus as the mucus plug comes away) can appear around now.

How it may feel

Often feels like period cramps, a dull low backache, or tightening that comes and goes. You can usually still talk, walk, and rest between contractions.

Roughly how long (every labor differs)

Frequently the longest and most variable part of labor — it can build over many hours and sometimes starts and stops across more than a day, especially with a first baby. There is no “normal” length.

What you can do

  • Rest and conserve energy; eat lightly and stay hydrated.
  • Time contractions to watch the trend, not any single one.
  • Call your provider with questions and follow the plan they gave you.

Going in

Most people spend early labor at home. Head in when your provider told you to, when contractions reach the pattern they set (often around 5-1-1), or sooner if any warning sign below appears.

First stage · Active labor

The cervix opens from about 6 cm to fully dilated

What's happening

The cervix opens from roughly 6 cm to fully dilated (10 cm). Contractions become stronger, longer, and closer together, and they no longer ease off when you move, rest, or change position.

How it may feel

Intense, regular contractions that take real focus and are hard to talk through. Low-back and pelvic pressure build as the baby moves down.

Roughly how long (every labor differs)

Usually moves along faster than early labor, but the pace still varies a great deal from person to person and pregnancy to pregnancy.

What you can do

  • Be where you plan to give birth if you aren't already.
  • Lean on breathing, movement, positions, and your support team.
  • Ask about pain-relief options if you want them.

Going in

If you're not already in your provider's care, this is the “go now” phase. From here, your birth team guides what happens next.

Second stage · Pushing & birth

Fully dilated to the birth of your baby

What's happening

From full dilation to the moment your baby is born. With each contraction you push and bear down, the baby moves down the birth canal, the head “crowns” (comes into view), and shortly after, your baby is born.

How it may feel

A strong urge to push or bear down and intense downward pressure. Many people find this stage more purposeful and active than the pain of active labor.

Roughly how long (every labor differs)

Can range from a few pushes to several hours, and is often longer with a first baby or with an epidural. Your provider or midwife guides the pace.

What you can do

  • Push with your contractions as your birth team guides you.
  • Rest fully between contractions to save energy.
  • Use the positions your provider or midwife suggests.

Going in

You're already in your birth team's care by this stage — they direct the pushing and monitor you and the baby throughout.

Third stage · Delivering the placenta

The placenta is delivered after the birth

What's happening

After your baby arrives, milder contractions return to deliver the placenta, and your provider clamps and cuts the umbilical cord. Your team checks that the placenta came away completely.

How it may feel

Much gentler contractions than the birth itself — often barely noticed while you're meeting your baby.

Roughly how long (every labor differs)

Usually the shortest stage, finishing soon after the birth. As always, the exact timing varies.

What you can do

  • Skin-to-skin contact and early feeding are often encouraged now.
  • Your team watches your bleeding and checks the placenta is intact.
  • Ask any questions about what comes next in recovery.

Going in

Your birth team watches closely for heavier-than-expected bleeding at this stage. You're fully in their care.

A timeline can't examine your cervix or tell you which stage you're in — only your provider can. When something feels off, call.

At a glance

The three stages, side by side

The stages themselves are standard; the timing column is deliberately kept in plain, relative terms because labor is highly variable and there is no dependable average to plan around.

The three stages of labor — stage, phase, what is happening, and a qualitative note on how long each tends to take (durations are highly variable)
Stage Phase What's happening Roughly how long
First stage Early (latent) Contractions begin; the cervix softens, thins, and opens to about 6 cm. Often the longest, most variable part — hours, sometimes on and off over more than a day.
First stage Active The cervix opens from about 6 cm to fully dilated (10 cm); contractions get stronger and closer. Usually faster than early labor, but still varies widely.
Second stage Pushing & birth Fully dilated to the birth — you push with contractions until your baby is born. A few pushes to several hours; often longer with a first baby or an epidural.
Third stage Afterbirth The placenta is delivered and the cord is cut. Usually the shortest stage.

When to go in

Knowing when it's time

For a full-term pregnancy, most of early labor is normally spent at home, and you generally head in as active labor establishes. The widely-taught rule of thumb is 5-1-1 — contractions about 5 minutes apart, each lasting about 1 minute, sustained for about 1 hour — but it's only a guide. Your provider may tell you 4-1-1, or to come in sooner because of your history, a fast previous labor, or how far you live from care. Their instruction always wins.

To read the pattern for yourself, two companion tools do the measuring this timeline doesn't: the contraction timer tracks how far apart and how long your contractions are, and the “Am I in labor?” checker helps sort true labor from false (practice) labor. If your provider has raised induction, the Bishop score calculator explains how “ready” the cervix is.

The rule that overrides the timeline

Every labor is different — and your provider's plan wins

This timeline is a map, not a schedule. Two people can pass through the exact same stages on completely different clocks — one over many hours of stop-and-start early labor, another far more quickly — and both can be entirely normal. First labors generally take longer than later ones, an epidural can change the feel and pace of pushing, and no calculator can predict where yours will land. That's why we keep every duration here qualitative and avoid pinning numbers on a process that refuses to be pinned.

So use this to understand the journey, not to grade your own progress. The people watching your specific labor — your obstetric provider or midwife, with a cervical exam this page can never do — are the only reliable guide to what stage you're in and what to do next. When you're unsure, when a warning sign appears, or when your instructions say so, call: being checked and reassured is the system working exactly as it should.

Where this comes from

The structure of the three stages — early (latent) and active first-stage labor, the second-stage pushing and birth, and the third-stage delivery of the placenta — follows MedlinePlus/NIH's overview of childbirth, which describes labor as happening in three stages and the first stage as one that “could last for hours or days.” ACOG's patient guidance on how to tell when labor begins informs the early signs of labor and the when-to-call cues. The roughly-6-cm threshold for active labor and the 10 cm full-dilation mark reflect current obstetric labor definitions. We keep all durations qualitative by design, we don't invent averages, and the preterm-labor warning (contractions before 37 weeks) follows ACOG's guidance on preterm labor.

Good to Know

Stages of labor: frequently asked questions

The three stages explained, why durations vary so much, the difference between early and active labor, when to go in, the warning signs that mean call now, and how private this guide is.

What are the stages of labor?

Labor happens in three stages. The first stage is the longest and has two parts: early (latent) labor, when contractions begin and the cervix softens, thins, and opens to about 6 cm; and active labor, when the cervix opens the rest of the way to fully dilated (10 cm) and contractions become stronger, longer, and closer together. The second stage runs from full dilation to the birth of your baby — this is the pushing stage, ending when your baby is born. The third stage is the delivery of the placenta shortly after the birth, when your provider also cuts the umbilical cord. This timeline walks through roughly what happens in each stage, but the way any individual labor moves through them varies enormously — the framework is standard, the schedule is not.

How long does each stage of labor last?

There is no reliable “average” to plan around, because labor is genuinely variable — which is why this guide keeps durations qualitative rather than putting a clock on them. In general terms: early (latent) labor is usually the longest and most unpredictable part and can unfold over many hours, sometimes starting and stopping across more than a day, especially in a first pregnancy; active labor typically moves faster than early labor but still varies a lot; the pushing stage can be anywhere from a few pushes to several hours and is often longer with a first baby or an epidural; and delivering the placenta is usually the shortest stage. First labors tend to take longer than later ones. The honest answer to “how long will mine take?” is that no one can say in advance — your provider, watching your specific labor progress, is the only reliable guide.

What's the difference between early (latent) and active labor?

They're the two phases of the first stage, and the practical difference is how far the cervix has opened and how the contractions feel. In early (latent) labor the cervix is softening, thinning, and dilating up to about 6 cm; contractions are usually milder and more spread out, and most people manage this phase at home while resting, eating lightly, and staying hydrated. Active labor begins around 6 cm and continues to full dilation at 10 cm; contractions become stronger, longer, and closer together, they no longer ease when you move or rest, and this is the phase to be where you plan to give birth. The roughly-6-cm dividing line reflects current obstetric guidance on when labor is considered active — but it's assessed by a cervical exam, which is something only your provider can do.

When should I go to the hospital or birth center?

For a full-term pregnancy, a lot of early labor is normally spent at home, and you generally head in as active labor establishes. A widely used rule of thumb is 5-1-1 — contractions about 5 minutes apart, each lasting about 1 minute, keeping that up for about 1 hour — but 5-1-1 is only a guide: your provider may tell you 4-1-1, or to come sooner, based on your history, how fast a previous labor went, and how far you live from care. Their instruction always wins. To get the numbers, use the contraction timer to measure the pattern, and the “Am I in labor?” checker to sort true labor from false (practice) labor. And regardless of any pattern, go in or call now if you have a warning sign — see the next question.

What warning signs during labor mean call now or go in?

Some things override the timeline entirely — call your provider or go to labor and delivery right away (or call emergency services), whatever your contractions are doing, if: your water breaks and the fluid is green, brown, or foul-smelling (a possible sign of meconium or infection — and whatever the color, call your provider any time your water breaks); you have heavy or bright-red vaginal bleeding, more than the light pink “bloody show”; your baby is moving less than usual; you feel the umbilical cord bulging into or slipping out of the vagina, or you can see it (a cord prolapse — call emergency services); you have severe, constant pain that never eases between contractions, or a sudden severe headache, vision changes, or belly pain; or you're having regular contractions before 37 weeks, which can be preterm labor. None of these are “wait and see” situations. When in doubt, call — being checked and reassured is exactly how the system is meant to work.

Is this tool private, and is it medical advice?

It's private: this page is a static guide that runs entirely in your browser. There's no account, no tracking of anything you do, and nothing is sent, saved, or shared — the interactive part just reveals one stage at a time on your own device. And it is not medical advice. It's general educational information based on ACOG and MedlinePlus guidance about the stages of labor; it can't examine you, it can't tell you which stage you're in, and it never replaces a cervical exam or the specific instructions your obstetric provider gave you. Every labor is different, and your provider's plan is the one to follow.
