Somewhere in the third trimester, your belly tightens, holds for a moment, then lets go — and your first thought is, is this it? That uncertainty is completely normal. Here’s how to tell Braxton Hicks “practice” contractions from the real thing, and when it’s time to call.
What are Braxton Hicks contractions?
Braxton Hicks are sometimes called “practice” contractions — your uterus tightening and relaxing as it warms up for labor, often from the second trimester onward and more noticeably as your due date nears. They’re a normal part of pregnancy, not a sign that anything is wrong.
Most people feel them as a tightening or squeezing across the front of the belly that comes and goes. They’re usually uncomfortable rather than truly painful, and — this is the key part — they don’t settle into a regular, intensifying pattern.
What do real labor contractions feel like?
Real contractions are the steady, building waves that open your cervix. The hallmark is a clear pattern that strengthens over time: each contraction tends to get longer, stronger and closer together, and they keep coming whatever you do.
Many people feel real contractions wrap from the back around to the front, with the intensity rising to a peak and then easing — more like a wave than a quick squeeze. Unlike practice contractions, they don’t politely stop when you rest or shift position.
Braxton Hicks vs real contractions: a side-by-side
The pattern matters more than any single contraction. Here’s the quick comparison:
| What to notice | Braxton Hicks | Real contractions |
|---|---|---|
| Timing | Irregular, unpredictable | Regular, getting closer together |
| Over time | Stay the same or fade | Get longer, stronger, closer |
| When you move/rest | Often ease or stop | Keep coming regardless |
| Where you feel it | Usually the front | Often wrap from back to front |
| Pain | Uncomfortable, not painful | Build to a real, intensifying ache |
If you read across one row and it sounds like the right-hand column, especially the timing, treat it as possible labor and follow your provider’s instructions.
How can I test whether it’s false labor?
Braxton Hicks often respond to a few simple things, while true labor doesn’t. It’s a gentle, no-pressure way to check before you call:
- Drink water. Dehydration can trigger practice contractions, so have a couple of glasses.
- Change position or rest. Lie down if you’ve been active, or get up and walk if you’ve been sitting. A warm bath can also help practice contractions ease.
- Empty your bladder. A full bladder can make tightenings more noticeable.
- Time them. Note when each one starts and how long it lasts. Our contraction timer does the counting for you and shows whether a pattern is forming.
If the tightenings fade with rest, water and time, they were most likely Braxton Hicks. If they keep coming, get closer together and grow stronger, that’s the picture of real labor.
What is the 5-1-1 rule, and when do I call?
For a full-term, low-risk pregnancy, many providers use a simple guide called 5-1-1: contractions about 5 minutes apart, each lasting around 1 minute, continuing for at least 1 hour. Reaching 5-1-1 is a common cue to call your provider or head to your birth place — but this is general guidance. Always follow the specific plan your own provider gave you, as your situation (distance to hospital, a prior fast labor, twins, and more) can change the advice.
When should I call my provider straight away?
Some things warrant a call right away, no timing required. Contact your provider or go in if:
- Your waters break (a gush or a steady trickle of fluid).
- You have any vaginal bleeding.
- You notice reduced or changed baby movements.
- You have regular, painful contractions before 37 weeks, which could be early labor.
- Something simply doesn’t feel right.
You never need to apologize for calling. Triage lines and maternity units expect these questions, and it’s always okay to check.
To get ready, our contraction timer makes it easy to spot a real pattern, and the hospital bag checklist helps you feel prepared for the day itself.
