GUIDE
Braxton Hicks are irregular practice contractions that help your uterus prepare for labor — they do not dilate your cervix or mean labor is starting.
These tightenings can feel startling the first time you notice them, but they are a normal part of pregnancy. Learning the difference between Braxton Hicks and real contractions will help you know when to stay calm and when to head to the hospital.
Be prepared from day one
Braxton Hicks contractions feel like your entire belly tightens and becomes firm — almost like a basketball. The sensation usually starts at the top of the uterus and spreads downward. They typically last 30 seconds to 2 minutes and are irregular, meaning the time between them varies. Most people describe them as uncomfortable rather than painful, though they can become intense in late pregnancy.
Your uterus is a muscle, and like any muscle, it practices the movements it will eventually need to perform. Braxton Hicks are your uterus rehearsing for labor — they tone the uterine muscle and may help increase blood flow to the placenta. They do not dilate the cervix or indicate that labor is imminent.
The key distinction from real labor is the pattern. Braxton Hicks are irregular, do not get progressively stronger, and usually stop when you change what you are doing. Real labor contractions follow a pattern: they come at regular intervals, get closer together over time, grow in intensity, and do not go away no matter what you try.
Braxton Hicks can start as early as week 20, though many people do not notice them until the third trimester. They become more frequent and noticeable in the weeks leading up to your due date — some people experience them several times a day in the last month.
If this is your first pregnancy, you may not recognize Braxton Hicks until someone describes what they feel like. Second-time parents often notice them earlier because they know the sensation. By mid-pregnancy, the uterus is large enough that these practice contractions become perceptible.
In the final weeks, Braxton Hicks can become frequent enough to feel like early labor — a phenomenon sometimes called "false labor" or prodromal labor. This is your body's dress rehearsal and while it can be frustrating, it is a sign that your body is preparing efficiently.
Since Braxton Hicks are a normal part of pregnancy, the goal is not to eliminate them but to manage discomfort and confidently distinguish them from real labor. These strategies help reduce their frequency and intensity.
Dehydration is the most common trigger for Braxton Hicks. Drinking 16 to 20 ounces of water often calms contractions within 15 to 30 minutes. If you notice Braxton Hicks picking up, your first step should always be hydration.
If you are standing, sit or lie down. If you are sitting, stand up and walk around gently. Braxton Hicks often respond to a change in activity or position. Real labor contractions will not stop regardless of what position you are in.
Warm water relaxes uterine muscles and can quiet Braxton Hicks contractions. A bath at body temperature (not hot — avoid water above 100 degrees F) for 15 to 20 minutes is both soothing and diagnostic: if contractions stop, they were Braxton Hicks.
Braxton Hicks are a good opportunity to practice the breathing techniques you may use during labor. Slow, deep breaths — in through the nose for 4 counts, out through the mouth for 6 counts — can help relax your body and reduce the intensity of the tightening.
A full bladder can irritate the uterus and trigger contractions. If you notice Braxton Hicks becoming frequent, try using the bathroom even if you do not feel an urgent need. Keeping your bladder from getting overly full can prevent some episodes.
These symptoms can occasionally signal something that needs medical attention. When in doubt, call.
Braxton Hicks are a sign that your body is doing exactly what it should — preparing for birth. They do not mean labor is near (though they do become more common as your due date approaches), and they are not harmful to you or your baby.
Learning to distinguish Braxton Hicks from real contractions is one of the most empowering things you can do in the third trimester. The simple rule: if contractions are irregular and stop with rest or water, they are almost certainly Braxton Hicks. If they follow a regular, intensifying pattern, it may be time to call your provider.

If you notice any bleeding along with contractions, see our guide on when that warrants a call. Our guides on round ligament pain and pregnancy discharge can also help you distinguish between different types of sensations in later pregnancy.
