Key Takeaways
- Braxton Hicks are "practice" contractions — irregular, usually painless, and don't open the cervix
- True labor contractions get stronger, longer, and closer together over time
- Braxton Hicks often ease when you move, rest, or hydrate; true labor doesn't
- Use the 5-1-1 rule as a general guide: contractions 5 minutes apart, lasting 1 minute, for 1 hour
- Call your provider for regular contractions before 37 weeks or if your water breaks
Somewhere in the second or third trimester, you'll feel your belly tighten and wonder: "Is this it?" For most people, those early tightenings are Braxton Hicks — your body's rehearsal for the real thing. Knowing how to tell them apart from true labor saves a lot of worry (and unnecessary trips to the hospital).

What Are Braxton Hicks?
Named after the doctor who first described them in 1872, Braxton Hicks contractions are intermittent tightenings of the uterine muscle. They're thought to tone the uterus and promote blood flow to the placenta. They can start as early as the second trimester but are most noticeable in the third.
They feel like a painless squeezing or hardening of the belly that comes and goes without a pattern. Dehydration, a full bladder, physical activity, or even sex can trigger them.
Braxton Hicks vs True Labor
| Feature | Braxton Hicks | True Labor |
|---|---|---|
| Pattern | Irregular, unpredictable | Regular, gets closer together |
| Intensity | Stays the same or fades | Steadily increases |
| Duration | Varies, often under 30 sec | Lengthens (30–70 sec) |
| Location | Front of the belly | Starts in the back, wraps around |
| Response to movement | Often stop with rest/water | Continue regardless |
How to Tell the Difference
When you feel contractions, run through this quick check:
- Change position — stand up, sit down, or lie on your side. Braxton Hicks often ease; true labor doesn't
- Drink a glass of water — dehydration is a common Braxton Hicks trigger
- Time them — note how long each lasts and how far apart they are. A tightening pattern points to real labor
- Notice the location — true labor often starts as a dull backache that radiates to the front
When in doubt, hydrate and rest
If you're unsure, lie down on your left side, drink water, and time contractions for an hour. If they fade, it was likely Braxton Hicks. If they intensify or get closer together, call your provider.
How to Ease Braxton Hicks
- Drink water — dehydration is the most common trigger
- Change your activity or position
- Empty your bladder
- Take a warm (not hot) bath
- Practice slow, deep breathing to relax
Timing Your Contractions
The widely used 5-1-1 rule is a general signal that active labor may be starting: contractions about 5 minutes apart, each lasting about 1 minute, continuing for at least 1 hour. Your provider may give you different instructions based on your pregnancy, how far you live from the hospital, and whether you've given birth before — always follow their guidance.
When to Call Your Doctor
- Regular, painful contractions before 37 weeks (possible preterm labor)
- Contractions that follow the 5-1-1 pattern at term
- Your water breaks — note the time, color, and amount
- Vaginal bleeding, decreased fetal movement, or severe pain
- Any contractions accompanied by fever or dizziness
FAQ
Can Braxton Hicks be painful?
They're usually described as uncomfortable rather than painful, but intensity varies. As you approach your due date, they can feel stronger. The key difference is that they don't follow a tightening, regular pattern like true labor.
When do Braxton Hicks start?
Some people notice them as early as 16 weeks, but they're most common and noticeable in the third trimester. First-time parents often feel them later than those who've been pregnant before.
Can Braxton Hicks turn into real labor?
Braxton Hicks themselves don't become labor, but "prodromal" or early labor contractions can feel similar at first. If tightenings become regular and intensify, time them and contact your provider.
