Braxton Hicks contractions are irregular, unpredictable tightenings of the uterus that stop when you change what you’re doing. The fastest way to tell if you’re having them: time the contractions and then go for a walk or change positions. If they fade or disappear, they’re almost certainly Braxton Hicks. If they get stronger, closer together, and more painful regardless of what you do, that’s a different story.
What Braxton Hicks Actually Feel Like
Most people describe Braxton Hicks as a tightening or squeezing sensation across the belly, almost like the uterus is balling up into a fist and then releasing. Your abdomen may feel noticeably hard to the touch during one. They’re uncomfortable, but they don’t build to the kind of pain that makes you stop what you’re doing or need to breathe through them.
The tightening tends to be felt in the front of the abdomen rather than wrapping around to the lower back. True labor contractions often start as a deep ache in the lower back that radiates forward, or they produce pressure low in the pelvis, as though the baby is pushing downward. Braxton Hicks rarely do either of those things.
Each Braxton Hicks contraction typically lasts less than a minute. You might get one or two in an hour, a few times a day, and then nothing for the rest of the evening. There’s no rhythm to them. They don’t build on each other the way labor does, where each wave arrives sooner and hits harder than the last.
The Movement Test
This is the single most useful thing you can do in the moment. If you’ve been sitting or lying down, stand up and walk around. If you’ve been active, sit or lie down and rest. Braxton Hicks contractions respond to changes in activity. They ease up or stop altogether when you shift positions.
True labor contractions don’t care what you’re doing. Walking, resting, taking a bath, switching sides in bed: none of it slows them down. In fact, real labor often intensifies with movement. If you’ve changed your activity and the contractions keep coming at regular intervals, pay closer attention to timing.
How to Time Your Contractions
Grab your phone or a clock and note when each contraction starts and how long it lasts. After four or five, look for a pattern. Braxton Hicks will be all over the place: one comes at 3:10, another at 3:25, maybe nothing until 4:00. The gaps are random and the duration varies.
Labor contractions settle into a recognizable rhythm. They become more frequent, last longer, and feel more intense over time. A widely used guideline is the 5-1-1 rule: when contractions come every 5 minutes, last 1 minute each, and maintain that pattern for 1 hour, it’s time to contact your provider. Your own care team may give you slightly different numbers, but 5-1-1 is a solid benchmark.
Common Triggers
Braxton Hicks don’t come out of nowhere. Dehydration is one of the most common triggers. If you notice tightening after a busy afternoon where you haven’t been drinking enough water, try a tall glass and see if they settle. A full bladder can also set them off, so emptying your bladder is worth trying as a first step.
Physical activity, sex, and even the baby moving around can all kick off a round of Braxton Hicks. They tend to be more frequent later in the day when you’re tired. Knowing your triggers helps you recognize the pattern: if contractions always show up after your evening walk and disappear once you sit down with a glass of water, that’s classic Braxton Hicks behavior.
When They Start in Pregnancy
Your uterus actually begins these practice contractions early in pregnancy, but most people don’t feel them until the second or third trimester. They become more noticeable and more frequent as you get closer to your due date, which is part of why the third trimester brings the most anxiety about whether “this is it.” Some people feel them often, others rarely notice them at all. Both are normal.
How to Get Relief
Because Braxton Hicks respond to changes in activity, relief is usually straightforward:
- Switch your activity. Walk if you’ve been resting. Rest if you’ve been moving.
- Drink water. Dehydration is a reliable trigger, and rehydrating often stops contractions within 15 to 20 minutes.
- Empty your bladder. A full bladder puts pressure on the uterus and can provoke tightening.
- Take a warm bath. The warmth helps relax uterine muscles.
- Practice slow breathing. Even though Braxton Hicks aren’t dangerous, the discomfort can feel unsettling. Controlled breathing helps your body relax.
Braxton Hicks vs. True Labor at a Glance
- Pattern: Braxton Hicks are irregular and unpredictable. Labor contractions become regular and get closer together.
- Intensity: Braxton Hicks stay mild to moderate and don’t escalate. Labor contractions grow stronger with each one.
- Duration: Braxton Hicks typically last under a minute and happen only a few times an hour. Labor contractions lengthen over time.
- Response to movement: Braxton Hicks stop or ease when you change positions. Labor contractions continue no matter what.
- Location: Braxton Hicks tend to be felt across the front of the belly. Labor contractions often involve lower back pain and pelvic pressure.
Warning Signs Before 37 Weeks
If you’re less than 37 weeks pregnant, the stakes of telling these apart go up. Preterm labor can look subtle at first, and some of its early signs overlap with what you might dismiss as Braxton Hicks. Contact your midwife or doctor right away if you notice any of the following before 37 weeks:
- Contractions happening more than four times in an hour
- A dull, persistent ache in your lower back that doesn’t go away with position changes
- Pressure low in the pelvis, as though the baby is bearing down
- Stomach cramps that feel like period pain
- Any fluid or blood coming from your vagina
- Nausea, vomiting, or diarrhea alongside contractions
- A noticeable decrease in the baby’s movement
If your water breaks before 37 weeks, whether it’s a gush or a slow trickle, call your provider or go to the hospital immediately. That’s true even if you aren’t feeling contractions yet.
