During early labor, contractions typically last about 30 to 45 seconds each. As labor progresses, they gradually lengthen, peaking at 60 to 90 seconds during the most intense phase right before pushing. How long each contraction lasts, how often they come, and how they change over time are the key signals that tell you where you are in the process.
Early Labor Contractions
Early labor is the longest and least intense phase. Contractions usually last 30 to 45 seconds and may start 15 to 20 minutes apart, gradually moving closer together. At this stage, many people describe them as feeling like strong menstrual cramps or a tightening across the belly. You can typically walk, talk, and stay at home through this phase.
The gap between contractions matters just as much as their length. In early labor, you might have 10 or even 20 minutes of rest between them. Over the course of hours, those gaps shorten and the contractions themselves grow a bit longer. Early labor can last anywhere from a few hours to a full day or more, especially with a first baby, so the gradual shift in timing is your best indicator that things are moving forward.
Active Labor and Transition
Once contractions reach about 45 seconds long and come every 3 to 5 minutes, you’ve entered active labor. They’re noticeably stronger now, and the rest periods between them feel shorter. Most people find it difficult to carry on a conversation during an active labor contraction.
The final stretch before pushing is called transition. This is the most intense part of labor, but also the shortest, often lasting 30 minutes to 2 hours. Contractions during transition last 60 to 90 seconds and come every 2 to 3 minutes. That leaves very little recovery time between them, which is why this phase feels overwhelming. It helps to know that reaching this level of intensity means delivery is close.
Contractions During Pushing
During the pushing stage, contractions continue at a similar length to transition, roughly 60 to 90 seconds, but many people experience them differently because the urge to push gives them something active to do. Your care team will guide you to push with each contraction or follow your body’s natural urge. The time between contractions may stretch slightly compared to transition, giving you brief rest periods. For first-time mothers, pushing can last anywhere from 20 minutes to a few hours.
Braxton Hicks vs. Real Contractions
Braxton Hicks contractions can start as early as the second trimester and often cause confusion about whether labor has begun. The key difference isn’t just how long they last, it’s what they do over time. Braxton Hicks contractions are irregular. They don’t get closer together, don’t grow stronger, and often stop entirely when you change position or start walking. They tend to stay in the front of your belly rather than wrapping around to your back.
Real labor contractions follow a pattern of progression: they get longer, stronger, and closer together. If timing them for an hour shows no consistent pattern or shortening interval, you’re likely dealing with Braxton Hicks.
Prodromal Labor: The Tricky Middle Ground
Prodromal labor sits between Braxton Hicks and true labor, and it fools a lot of people. These contractions can be mildly painful, come as often as every five minutes, and last up to 60 seconds each. That sounds like real labor on paper. The difference is that prodromal labor never advances beyond this point. The contractions don’t get stronger or closer together, and they don’t cause the cervix to dilate.
Prodromal labor can come and go for days or even weeks before true labor starts. It’s physically and emotionally exhausting, but it’s not dangerous. The clearest sign that contractions have shifted from prodromal to real labor: they start lasting longer than one minute, come closer than every five minutes, and maintain that pattern for over an hour straight.
When Contraction Timing Signals It’s Time to Go
Most hospitals and birth centers use a simple timing guideline. For a first baby, head in when contractions come every 3 to 5 minutes, last at least 45 to 60 seconds each, and hold that pattern for about an hour. If you’ve given birth before, the threshold is a bit more relaxed: contractions every 5 to 7 minutes lasting 45 to 60 seconds, because labor tends to progress faster after the first time.
A contraction timer app can make tracking easier, but all you really need is a clock. Note when each contraction starts, how long it lasts, and how much time passes before the next one begins. The pattern over an hour tells you more than any single contraction does.
Afterpains: Contractions After Delivery
Contractions don’t end with delivery. After the baby is born, your uterus continues to contract as it shrinks back toward its pre-pregnancy size. These afterpains feel like strong cramps and are most intense in the first few days postpartum. They often feel stronger during breastfeeding, because nursing triggers the same hormone that causes contractions.
Afterpains tend to be more noticeable with second or subsequent pregnancies, since the uterus has more work to do to return to size. The most intense cramping usually fades within a few days, though milder sensations can linger for a week or two as the uterus continues to heal.
