Contractions during early labor typically last 30 to 45 seconds each. They start out mild and irregular, often spaced 15 to 20 minutes apart, then gradually become longer, stronger, and closer together as labor progresses. This early phase, known as the latent phase, is usually the longest part of labor and can stretch up to 20 hours for a first-time mother.
What Early Contractions Feel Like
Early labor contractions often feel similar to menstrual cramps. The pain usually starts in your back and moves toward the front of your abdomen as your uterus tightens and releases. At first, contractions may be mild enough that you can walk, talk, and go about your day. As the latent phase progresses, they become more intense, and you may need to pause and breathe through them.
Each contraction has a wave-like pattern: it builds to a peak of tightness, holds briefly, then fades. In the earliest stage, that entire wave lasts roughly 30 to 45 seconds. By the time you’re transitioning out of early labor and into active labor, contractions typically last closer to 60 seconds and arrive every three to five minutes.
How Long the Early Phase Lasts Overall
The latent phase is the most unpredictable part of labor. For first-time mothers, it can last up to about 20 hours and still be considered within normal range. For someone who has given birth before, the upper limit is closer to 14 hours. Many people experience a much shorter early labor than these maximums, but the wide range is normal, and a long latent phase on its own is not a sign of a problem.
During this time, your cervix gradually opens from closed to about 6 centimeters dilated. Progress can be slow and uneven, with contractions sometimes stalling or spacing out before picking back up again.
How to Time Your Contractions
Two numbers matter when you’re tracking contractions: how long each one lasts and how far apart they are. To measure duration, start timing when you feel the tightening begin and stop when it fully releases. To measure frequency, time from the start of one contraction to the start of the next, not from the end of one to the beginning of the next.
A contraction timer app can make this easier, but a clock with a second hand works fine. Track at least four or five contractions in a row to get a reliable pattern, since early labor contractions are often irregular. You may have one that comes after 10 minutes, the next after 7, and another after 12. That inconsistency is typical of the latent phase.
Many providers recommend heading to the hospital when contractions follow a 5-1-1 pattern: coming every 5 minutes, lasting 1 minute each, and continuing at that pace for at least 1 hour. Until you reach that threshold, you’re generally still in early labor.
Early Labor vs. Braxton Hicks
Braxton Hicks contractions can feel convincingly real, especially in the final weeks of pregnancy, but they differ from true early labor in several important ways:
- Pattern: Braxton Hicks contractions are irregular and don’t get closer together over time. True labor contractions follow a pattern that steadily tightens.
- Response to movement: Walking or changing positions usually makes Braxton Hicks stop. Real contractions continue or intensify when you move.
- Intensity: Braxton Hicks may feel uncomfortable but rarely prevent you from carrying on normally. True contractions get progressively stronger, eventually making it difficult to talk through them.
- Location: Braxton Hicks tend to concentrate in the front of your belly. Real labor pain often starts in your back and radiates through your lower abdomen and pelvis.
- Accompanying signs: True labor may come with other signals like losing your mucus plug, a bloody show, or your water breaking. Braxton Hicks typically occur on their own.
What to Do During Early Labor
Since the latent phase can last many hours, conserving energy matters. Rest when you can, eat light meals, and stay hydrated. Gentle movement like walking or swaying on a birth ball can help you stay comfortable and may encourage labor to progress. A warm bath or shower often eases the cramping sensation of early contractions.
This is also a good time to finish any last preparations, charge your phone, and make sure your hospital bag is ready. There’s no need to rush to the hospital while contractions are still short (under a minute), mild, and spaced more than five minutes apart. Arriving too early often means being sent home or spending long hours waiting in a less comfortable environment. Use the timing pattern of your contractions as your guide for when it’s time to go.
