Braxton Hicks contractions are irregular, don’t get stronger over time, and eventually fade on their own. Real labor contractions come at steady intervals, grow progressively closer together, and intensify until delivery. That core difference in pattern is the single most reliable way to tell them apart at home, but several other clues help too.
Timing and Pattern
The biggest giveaway is regularity. True labor contractions settle into a predictable rhythm. They come at roughly even intervals, and those intervals shorten as labor progresses. Each contraction also lasts longer as things move along, typically between 30 and 90 seconds.
Braxton Hicks follow no pattern. They might come twice in ten minutes, then not again for an hour. They can last anywhere from less than 30 seconds to about 2 minutes, with no consistency from one to the next. They never build toward anything. They may feel more frequent toward the end of pregnancy, but they still won’t march steadily closer together the way real contractions do.
If you’re timing contractions and they seem to space back out after a while, that’s a strong sign you’re dealing with Braxton Hicks.
How They Feel
Braxton Hicks are more uncomfortable than painful. Most people describe them as a tightening or hardening across the front of the belly, like the uterus is squeezing and then releasing. They tend to stay mild or moderate.
True labor contractions are genuinely painful, and the pain builds. Each one is stronger than the last. Many people feel them start in the lower back and wrap around to the front of the abdomen. Some experience what’s called back labor, where intense pain and muscle spasms concentrate in the lower back and can radiate into the hips. That radiating quality, where the sensation moves rather than staying in one spot, is more characteristic of real labor.
What Happens When You Move or Rest
One of the simplest home tests: change what you’re doing. If you’ve been sitting, stand up and walk around. If you’ve been active, lie down and drink a glass of water. Braxton Hicks often ease up or disappear entirely with a change in activity or position. They lessen, fade, and then may pop up again later.
Real labor contractions don’t care what you’re doing. Walking, resting, changing positions, or drinking water won’t slow them down. If anything, movement can make them feel stronger.
What’s Happening to Your Cervix
This is the difference that actually matters medically. Braxton Hicks don’t cause any changes to your cervix. It stays the same thickness and stays closed. Real labor contractions thin your cervix (a process called effacement) and open it (dilation). That progressive opening is what defines true labor, and it’s the reason a cervical check is the only way to know with absolute certainty whether you’re in labor.
You can’t check this yourself at home. But knowing that cervical change is the gold standard helps explain why some contractions that feel real can still turn out to be false labor.
The Tricky Middle Ground: Prodromal Labor
Sometimes contractions fall into a frustrating gray area. Prodromal labor is a type of false labor that mimics the real thing more convincingly than basic Braxton Hicks. Contractions can come as often as every five minutes, last up to a minute each, and feel mildly painful. By any clock, that looks like early labor.
The catch: prodromal labor never advances beyond that point. The contractions don’t get closer together than every five minutes, they don’t intensify, and they don’t dilate your cervix. Think of it as a dress rehearsal. Your body is warming up for the real event, but the event hasn’t started. Prodromal labor can last hours or even recur over several days, which is understandably exhausting. The only definitive way to rule it out is a cervical check showing no dilation.
Other Signs That Point to Real Labor
Contractions aren’t the only signal. Real labor often comes with additional changes that Braxton Hicks don’t produce:
- Bloody show. A brownish or blood-tinged discharge means your cervix is starting to change. The mucus plug that sealed the cervix during pregnancy may come out as a visible clump. This is a positive sign, though active labor can still be hours or days away.
- Fluid leaking. A gush or steady trickle of clear fluid suggests your water has broken.
- Pressure low in the pelvis. As the baby drops, many people feel increasing heaviness or pressure deep in the pelvis that wasn’t there before.
Braxton Hicks contractions are not accompanied by bleeding, leaking fluid, or changes in fetal movement. If you notice any of those alongside contractions, that’s a meaningful distinction.
When Timing Says It’s Time
For a first baby, the general guideline is to head to the hospital when contractions come every 3 to 5 minutes, last 45 to 60 seconds each, and hold that pattern for at least an hour. If you’ve given birth before, the threshold is a bit wider: contractions every 5 to 7 minutes lasting 45 to 60 seconds, because labor tends to progress faster with subsequent pregnancies.
If you’re unsure, calling your provider first can save you a trip. They can walk you through what you’re feeling and tell you whether to come in.
Contractions Before 37 Weeks
Everything above applies to full-term pregnancy. Before 37 weeks, the rules change. Any regular contractions, even mild ones, need attention because they could signal preterm labor. The threshold to watch for is six or more contractions in a single hour, or contractions coming every 10 minutes or more often. Fluid or blood leaking from the vagina at any point before 37 weeks is another reason to call immediately.
Some Braxton Hicks in the second and third trimesters are completely normal. The concern is when they shift from occasional and random to frequent and patterned well before your due date.
Quick Comparison
- Pattern: Braxton Hicks are irregular and unpredictable. Real contractions are rhythmic and get closer together.
- Intensity: Braxton Hicks stay the same or fade. Real contractions get progressively stronger.
- Location: Braxton Hicks are usually felt as tightness in the front of the belly. Real contractions often radiate from the back to the front.
- Response to rest: Braxton Hicks ease with a change in activity. Real contractions continue regardless.
- Cervical change: Braxton Hicks cause none. Real contractions thin and open the cervix.
- Other symptoms: Braxton Hicks come alone. Real labor may bring bloody show, fluid leaking, or increasing pelvic pressure.
