Braxton Hicks vs. Real Contractions: How to Tell the Difference
Key takeaways
- Braxton Hicks are "practice" contractions that can start as early as the second trimester, though plenty of people never notice them at all.
- They feel like mild cramping or tightening, stay irregular, and typically ease off with rest, water, or a change in position.
- Real labour contractions do the opposite — they get longer, stronger, and closer together over time, and rest doesn't stop them.
- I never experienced Braxton Hicks during my own pregnancy — not feeling them is just as normal as feeling them from 20 weeks on.
- If you're genuinely unsure which you're feeling, timing contractions for an hour tells you more than judging the intensity alone.
I spent a chunk of my third trimester half-expecting Braxton Hicks to show up any week, based on how often they come up in pregnancy content — week 32 is a common point for them to start, by most accounts. They never did, not once, for me. If you’re in the same position, this is your reminder that it’s a completely normal way for a pregnancy to go, not a sign anything is missing.
What Braxton Hicks actually are
Braxton Hicks contractions are irregular tightenings of the uterus that some people start noticing as early as the second trimester, though they’re most common in the third. The exact cause isn’t fully settled, but they’re generally understood as the uterus doing a kind of rehearsal for labour. Dehydration, a full bladder, being especially active, sex, and lifting something heavy are all commonly reported triggers.
They typically feel like mild menstrual cramps or a tightening across the front of the belly — uncomfortable rather than painful, and mild enough that you can usually keep talking and walking through one without much trouble.
The real test: do they build, or fade
This is the single most useful thing to know, and it’s simpler than most descriptions make it sound. The NHS’s own comparison puts it plainly: Braxton Hicks don’t last long, don’t happen very frequently, and don’t build up — while real labour contractions get longer, stronger, and more frequent as labour goes on. Rest, water, and changing position will often calm Braxton Hicks down within a while. None of that touches real labour contractions once they’re properly underway.
If you’re genuinely unsure which one you’re feeling, the most reliable thing to do isn’t to judge the intensity in the moment — it’s to time them. Note how long each one lasts and how far apart they are, then check again in an hour. Braxton Hicks tend to stay scattered and unpredictable across that hour. Real contractions tend to show a pattern.
What actually helps if they’re bothering you
If Braxton Hicks are frequent enough to be genuinely uncomfortable, the usual relief methods are simple and worth trying in this order: change position or go for a short walk if you’ve been sitting still, or rest if you’ve been active; drink a full glass of water, since dehydration is a common trigger; empty your bladder; and if none of that settles things, a warm bath or a bit of quiet, calm downtime often does.
When to stop assuming it’s “just” Braxton Hicks
If contractions start coming at regular intervals, getting closer together, and not responding to rest or water, treat that as the real thing rather than continuing to wait it out. We’ve written separately about the fuller set of signs labour has actually begun — waters breaking, a “show,” and persistent back pressure alongside contractions — and when each of those is worth an actual call to your midwife.
Frequently asked questions
When do Braxton Hicks usually start?
They can begin as early as the second trimester, though most people don’t notice them until the third. Plenty of people never notice them at all, which is equally normal.
How can I tell if it’s Braxton Hicks or early labour?
Braxton Hicks stay irregular, don’t intensify, and usually ease off with rest, water, or a position change. Real contractions get longer, stronger, and closer together over time, and rest doesn’t make them stop.
Is it normal to never feel Braxton Hicks at all?
Yes, completely. I didn’t experience any myself. Whether or how strongly you notice them varies enormously between pregnancies and doesn’t predict anything about your actual labour.
What triggers Braxton Hicks?
Common triggers include dehydration, a full bladder, being very physically active, sex, and lifting something heavy — though sometimes there’s no obvious trigger at all.
Should I call my midwife if I’m not sure which I’m feeling?
Yes — if you’ve timed contractions for an hour and you’re still unsure, or if anything about how you’re feeling concerns you, calling is always the right move. It’s what your care team is there for.
