Labor happens in three distinct stages: the first stage is when your cervix opens (dilates) from 0 to 10 centimeters, the second stage is when you push your baby out, and the third stage is delivering the placenta. The entire process can take anywhere from a few hours to over 24 hours, depending largely on whether this is your first birth. Here’s what happens during each stage and what you can expect to feel.
Stage 1: Your Cervix Opens
The first stage is the longest part of labor. It begins when you start having regular contractions and ends when your cervix is fully dilated to 10 centimeters. Two things happen simultaneously during this stage: your cervix thins out (called effacement, measured from 0% to 100%) and it opens wider. Women who reach full effacement earlier tend to dilate faster once active labor kicks in.
This stage breaks into two phases that feel very different from each other.
Early (Latent) Labor: 0 to 6 Centimeters
Early labor is the slow buildup. Contractions may start irregular and mild, feeling like menstrual cramps or a tightening across your whole uterus that can radiate into your back. Over time they become more regular and intense. This phase can last up to 20 hours for a first baby and up to 14 hours for subsequent births, though many women experience it as a much shorter stretch.
This is typically the phase you spend at home. For a first baby, the general guideline is to head to the hospital when contractions come every 3 to 5 minutes and last 45 to 60 seconds over the course of an hour. If you’ve given birth before, contractions every 5 to 7 minutes at that same duration are the signal to go in, since things tend to speed up faster the second time around.
One useful distinction during this time: Braxton Hicks contractions (sometimes called “practice contractions”) have no regular pattern, don’t last longer than an hour as a sequence, go away if you move around, and aren’t truly painful. Real labor contractions get progressively closer together and stronger, and they don’t stop when you change positions.
Active Labor: 6 to 10 Centimeters
Active labor is when things intensify. Current guidelines define this phase as starting at 6 centimeters of dilation. Contractions become longer, stronger, and closer together. Most women dilate between 1 and 2 centimeters per hour during active labor, with those who have given birth before progressing on the faster end of that range.
The tail end of active labor, sometimes called transition, covers roughly the last few centimeters (around 7 or 8 cm to 10 cm). This is widely considered the most intense part of the entire labor process. Contractions may come every 2 to 3 minutes and last over a minute. Nausea, shaking, and an overwhelming urge to push are common. The good news: transition is also the shortest part of the first stage, often lasting 30 minutes to 2 hours.
Stage 2: Pushing and Delivery
Once your cervix reaches 10 centimeters, you enter the pushing stage. Your body may give you a strong, involuntary urge to bear down with each contraction. Some women feel a brief lull between full dilation and the start of this urge, sometimes called “laboring down,” which gives the baby time to descend further on its own.
During this stage, each contraction helps move the baby down through the birth canal. Your baby rotates as it descends, fitting through the narrowest parts of your pelvis. You’ll likely feel intense pressure in your lower pelvis and rectum. Many women describe a burning or stretching sensation as the baby’s head crowns (becomes visible at the vaginal opening).
How long this stage lasts varies widely. For first-time mothers, pushing can take anywhere from 20 minutes to a few hours. Women who have delivered vaginally before often push for a shorter time, sometimes just a few contractions. Whether you have an epidural also matters, since reduced sensation can make it harder to coordinate your pushing efforts, which sometimes extends this stage.
Throughout the first and second stages, your care team monitors the baby’s heart rate, usually with two external sensors placed on your abdomen: one over the baby’s heart and one near the top of your uterus to track contractions. For low-risk pregnancies, this monitoring can be intermittent rather than continuous, giving you more freedom to move around.
Stage 3: Delivering the Placenta
After your baby is born, you still have one more delivery. The third stage covers the separation and expulsion of the placenta from your uterine wall. Your uterus continues to contract, though these contractions are much milder than what you just experienced. You may be asked to give a few gentle pushes, or the placenta may pass on its own.
This is the shortest stage by far. The average duration is about 6 minutes, with most women delivering the placenta within 5 minutes. It can take up to 30 minutes and still be considered normal. Your care team will examine the placenta afterward to make sure it came out completely, since retained tissue can cause complications like heavy bleeding.
You may feel a gush of blood and fluid as the placenta separates. Some shaking or chills after delivery are also normal. If you plan to breastfeed, this is often when your baby is placed skin-to-skin on your chest for the first time, which can also help your uterus contract and reduce bleeding.
The “Fourth Stage”: Immediate Recovery
While labor is officially described in three stages, many providers recognize a fourth stage covering the two to three hours immediately after the placenta is delivered. During this window, your uterus begins to firm up and shrink, your care team watches for abnormal bleeding, and any tears or incisions are repaired.
This is also when the initial wave of postpartum hormones hits. Many women feel a rush of alertness, relief, or euphoria, though exhaustion and emotional overwhelm are equally common. Your vital signs will be checked frequently during this period, and you may notice cramping as your uterus continues to contract down toward its pre-pregnancy size, a process that continues over the following weeks.
