True preterm labor cannot be reliably stopped at home. If you’re having regular contractions before 37 weeks, the safest thing you can do is call your healthcare provider while trying a few simple measures: drinking water, lying on your left side, and emptying your bladder. These steps can calm contractions caused by dehydration or overexertion, but they won’t stop genuine labor where your cervix is changing. The difference matters enormously, because every hour gained before a preterm birth gives medical teams more time to protect your baby.
Why Home Remedies Have Limits
The idea of stopping preterm labor at home usually comes down to two strategies: hydration and rest. There’s a physiological reason hydration sometimes works. When your blood volume drops, your body may release more of the hormone that triggers contractions. Drinking fluids can expand blood volume, increase blood flow to the uterus, and potentially decrease production of the compounds that stimulate contractions. This mechanism has been demonstrated in animal models, and it’s the basis for the common advice to drink two or three large glasses of water when you notice tightening.
But here’s the critical distinction: hydration can quiet irritable uterine activity that isn’t true labor. If your cervix is actually dilating or thinning, water and rest won’t reverse that process. And you have no way to check your cervix at home. That’s why these measures should buy you time while you contact your provider, not replace medical evaluation.
As for bed rest, it’s one of the most commonly prescribed interventions for preterm labor risk, yet the evidence doesn’t support it. A Cochrane review found that preterm birth rates were essentially identical whether women were put on bed rest or not: 7.9% in the bed rest group versus 8.5% in the control group. The reviewers concluded there is no evidence either supporting or refuting bed rest for preventing preterm birth. It remains widely recommended more out of tradition than data.
Braxton Hicks vs. True Preterm Labor
Before you panic, it helps to know that many contractions before 37 weeks are Braxton Hicks, which are practice contractions that don’t change your cervix. Here’s how to tell the difference:
- Pattern: Braxton Hicks contractions are irregular and don’t get closer together. True labor contractions come at regular intervals and progressively shorten the gap between them.
- Duration: Braxton Hicks may last anywhere from under 30 seconds to 2 minutes, with no consistent pattern. True labor contractions last 30 to 90 seconds and get longer over time.
- Intensity: Braxton Hicks stay the same strength or fade away. True contractions build in intensity.
- Location: Braxton Hicks are typically felt in the front of the abdomen or one isolated spot. True labor starts in your mid-back and wraps around to the front.
- Response to movement: Braxton Hicks often stop when you change position, walk around, or lie down. True labor contractions continue or get stronger regardless of what you do. If you can sleep through a contraction, it’s almost certainly Braxton Hicks.
Time your contractions for an hour. If you’re getting four or more in 20 minutes, or six or more in an hour, and they don’t stop with hydration and rest, call your provider.
What to Do Right Now
If you’re feeling regular tightening or cramping before 37 weeks, take these steps in order:
- Drink 16 to 32 ounces of water over 15 to 20 minutes. Dehydration is one of the most common triggers for uterine irritability.
- Lie on your left side. This position improves blood flow to your uterus and may reduce contraction frequency.
- Empty your bladder. A full bladder can irritate the uterus.
- Time your contractions for one hour, noting when each one starts and how long it lasts.
- Call your provider if contractions don’t stop within an hour, if they’re getting stronger or closer together, or if you notice any fluid leaking or bleeding.
Do not wait to see if things “get better on their own” for hours. The window for medical intervention is narrow, and the treatments hospitals can offer work best when started early.
Warning Signs That Need Immediate Care
Certain symptoms mean you should head to the hospital rather than wait at home. Any vaginal bleeding heavier than light spotting needs immediate evaluation. A gush or steady trickle of fluid from your vagina could mean your membranes have ruptured. Increased vaginal discharge that’s clear, pink, or tinged with blood may signal that your mucus plug has passed, which can happen days before labor or at the start of it.
Intense pelvic pressure, especially if it feels like your baby is pushing downward, or low back pain that comes and goes in waves are also reasons to get evaluated quickly. These signs suggest cervical change may already be happening.
What Happens at the Hospital
Understanding what medical teams can do helps explain why getting there matters so much. The goal of hospital treatment isn’t necessarily to stop labor permanently. It’s to delay delivery by 48 hours to seven days, and that short window can dramatically change outcomes for your baby.
The most important intervention during that window is a course of corticosteroids to accelerate your baby’s lung and brain development. A single course reduces the risk of the most dangerous breathing complication in preterm babies by 34%, cuts the risk of brain bleeding by 46%, and lowers the chance of a serious intestinal complication by 54%. Neonatal death risk drops by 31%. These benefits peak when delivery happens between 24 hours and seven days after the first injection. Long-term studies show a 51% reduction in developmental delay during childhood among babies whose mothers received this treatment.
To buy that critical time, doctors use medications that quiet uterine contractions. These drugs work through different mechanisms: some block calcium from entering uterine muscle cells, others reduce the hormones that drive contractions. They’re typically given for about 48 hours, long enough for the corticosteroids to take effect and, if needed, for you to be transferred to a hospital with a neonatal intensive care unit.
Why Every Week of Pregnancy Counts
Babies born even a few weeks early face a cascade of challenges because their organ systems are still developing. The lungs, brain, and cardiovascular system are especially vulnerable. Preterm infants are at higher risk for breathing difficulties, brain injuries that can lead to cerebral palsy or intellectual disability, serious infections, kidney underdevelopment, and problems with hearing, vision, and sleep.
The neonatal intensive care environment itself poses risks. The immature nervous system, still in a sensitive stage of development, gets overloaded by continuous light, noise, painful medical procedures, and separation from parents. These stressors can affect neurodevelopment on top of the biological immaturity. Each additional day in the womb avoids some of this exposure and gives organs more time to mature.
Reducing Your Risk Going Forward
If you’ve had an episode of preterm contractions that resolved, or if you have a history of preterm birth, there are some evidence-based strategies for the remainder of your pregnancy. Staying well-hydrated is a simple, ongoing measure. Avoiding prolonged standing or strenuous physical exertion may help, though the evidence is stronger for avoiding extremes than for strict activity restriction.
For women with a prior preterm birth and a shortened cervix confirmed on ultrasound, vaginal progesterone may help maintain the pregnancy. However, the American College of Obstetricians and Gynecologists updated their guidance in 2023 to clarify that progesterone is not effective for preventing recurrent preterm birth when the cervix is a normal length. This means it’s not a blanket treatment for anyone with a prior preterm delivery. Your provider can measure your cervical length by ultrasound to determine whether this option applies to you.
The most important thing you can do at home is learn to recognize the difference between harmless Braxton Hicks contractions and the real thing, stay hydrated, and act quickly when something feels different. The simple measures you can take at home aren’t a substitute for medical evaluation, but they can help you arrive at the hospital with more time on the clock for the interventions that genuinely protect your baby.
