During a contraction, your belly visibly tightens and becomes noticeably hard to the touch. Depending on the type and intensity, you may see your abdomen change shape, sometimes looking lopsided or pointed as the uterine muscles squeeze. But contractions aren’t just something you see on the outside. They also follow distinct patterns of pain, timing, and intensity that change as labor progresses.
How Contractions Look From the Outside
When a contraction hits, the muscles of your uterus contract and push inward, which makes your entire belly firm up. If you placed your hand on your stomach during one, it would feel like pressing on a hard ball. Between contractions, your belly relaxes and feels soft again.
With Braxton Hicks contractions (the “practice” kind that happen before real labor), you’ll often see a tightening across the middle of your abdomen that can make your belly look lopsided and hard. These are sometimes visible enough that someone watching could notice the shape change. During true labor contractions, the hardening tends to be more uniform across the entire belly, and the tightening is stronger and more pronounced. Some people notice their belly rises or shifts forward slightly with each wave.
What Contractions Feel Like
Early labor contractions tend to be mild. Many people compare them to menstrual cramps or a dull ache low in the abdomen. They may not happen consistently at first, and you might be unsure whether you’re actually in labor.
As labor moves into the active phase, contractions become stronger, closer together, and more consistent. The sensation shifts from a manageable tightness to a deep, building pressure that peaks and then releases. By the transition phase (the final stretch before pushing), contractions come very close together and can last 60 to 90 seconds each. This is typically the most intense part of labor.
Not all contractions center on the front of your belly. In back labor, which happens when the baby is facing forward instead of toward your spine, pain concentrates in the lower back and tailbone. People describe back labor as intensely painful, sometimes excruciating, with spasms that can radiate into the hips. Unlike regular contractions that come and go with a clear break in between, back labor pain may feel nearly constant, worsening with each contraction without fully letting up.
How to Tell Real Contractions From False Ones
Braxton Hicks contractions can feel convincing, especially late in pregnancy. The key differences come down to pattern, intensity, and what makes them stop.
- Pattern: True labor contractions come at regular intervals and get closer together over time. False contractions have no consistent pattern and don’t progress.
- Intensity: Real contractions steadily get stronger. Braxton Hicks stay about the same or may even weaken.
- Response to rest: If you lie down, drink water, or change position and the contractions ease up or stop, they’re not real labor. True labor contractions continue regardless of what you do.
A simple test: time your contractions and note whether they keep coming when you’re resting and hydrated. If rest and water make them go away, you’re not in labor yet.
Contraction Timing as Labor Progresses
Contractions follow a predictable acceleration through the stages of labor. In early labor, they may be irregular and spaced 15 to 20 minutes apart. As active labor begins, they settle into a regular rhythm about three to five minutes apart. During the second stage of labor (pushing), contractions come every two to five minutes and last 60 to 90 seconds each.
The widely used guideline for heading to the hospital is the 5-1-1 rule: go when your contractions are 5 minutes apart, each one lasts 1 minute, and this pattern has continued consistently for at least 1 hour. Some providers use a 4-1-1 variation, so it’s worth confirming with yours ahead of time.
Signs That Need Immediate Attention
Most contractions are a normal part of the process, but certain accompanying signs call for an urgent call to your provider. Contact your hospital or midwife right away if your water breaks, you have vaginal bleeding, your baby is moving less than usual, or you’re less than 37 weeks pregnant and think labor has started. Contractions lasting longer than 2 minutes or coming six or more times in a 10-minute window also warrant an immediate call, even in the middle of the night.
