If you notice signs of early labor before 37 weeks of pregnancy, call your healthcare provider immediately. Prompt medical treatment can sometimes delay delivery long enough to give your baby’s lungs and other organs more time to develop. Treatments may include medications to slow contractions, steroids to speed lung growth, and close monitoring in a hospital. Do not try to stop labor at home on your own—early labor is a medical situation that needs professional evaluation.
What are the signs of early labor?
Early labor, also called preterm labor, happens when regular contractions cause the cervix to open before week 37 of pregnancy. The most common signs include contractions every 10 minutes or more often, a dull low backache, pelvic pressure, and cramps that feel like a menstrual period. You may also notice a change in vaginal discharge—watery fluid, mucus tinged with blood (called the bloody show), or a sudden gush of fluid from your vagina.
Not all contractions mean labor. Braxton Hicks contractions are irregular, usually painless, and do not cause cervical change. True labor contractions come at regular intervals, grow stronger over time, and do not stop when you change position or rest. If you are unsure, it is always safer to call your provider.
What causes early labor?
In many cases the exact cause is unknown. Known risk factors include having a previous preterm birth, carrying twins or more, infections of the uterus or urinary tract, a short cervix, smoking, high blood pressure, and diabetes. Certain lifestyle factors such as high stress, lack of prenatal care, and being underweight or overweight before pregnancy can raise the risk as well. However, many women who have preterm labor have none of these risk factors.
Infections are one of the most common treatable causes. Bacterial vaginosis, urinary tract infections, and some sexually transmitted infections can trigger an inflammatory response that leads to early contractions. Treating these infections early may lower the risk, but does not guarantee prevention.
How to stop early labor signs and treatments
When preterm labor is diagnosed, the main goal is to delay delivery long enough for corticosteroids to work—these medicines help speed up fetal lung development and reduce the risk of breathing problems after birth. Corticosteroids are most effective when given between 24 and 34 weeks of pregnancy. They are not a treatment to stop labor itself.
Medications called tocolytics are used to temporarily slow or stop contractions. Common tocolytics include nifedipine (a calcium channel blocker), terbutaline (a beta‑agonist given as an injection), and magnesium sulfate. Tocolytics can usually delay delivery by 48 hours to several days. This window allows steroids time to take effect and lets doctors transfer the mother to a hospital with a neonatal intensive care unit (NICU) if needed.
Magnesium sulfate is also given for a different reason: it lowers the baby’s risk of cerebral palsy if birth occurs before 32 weeks. It is not used primarily to stop contractions, but it can help calm the uterus.
In some cases, if the cervix is short and the waters have not broken, a doctor may place a stitch in the cervix (cerclage) to keep it closed. This is done only for cervical insufficiency, not for all preterm labor.
There is no evidence that drinking extra water, resting in bed, or avoiding sex can stop early labor once it has started. These measures may help with comfort but should never replace medical evaluation.
Does bed rest prevent preterm labor?
For decades doctors prescribed bed rest to prevent preterm labor, but major studies have found no clear benefit. Bed rest does not reduce the risk of preterm birth and can actually cause harm, including blood clots in the legs, muscle loss, and depression. The American College of Obstetricians and Gynecologists recommends against routine bed rest for preventing preterm labor.
Some clinicians still suggest reducing physical activity or avoiding heavy lifting, especially for women with a short cervix or a history of preterm birth. But these are not proven to stop active labor. If you are told to rest, ask your doctor what specific activities to avoid and for how long.
When should you go to the hospital?
Call your provider or go to the hospital if you have any of these signs before 37 weeks: contractions that come every 10 minutes or more often for an hour, a trickle or gush of fluid from the vagina, vaginal bleeding, pelvic pressure that feels like the baby is pushing down, or low back pain that does not go away. The sooner you are evaluated, the more options your medical team may have.
At the hospital, a nurse will check whether your cervix has started to open. A sterile speculum exam can test for leaking amniotic fluid. A fetal monitor will track your contractions and your baby’s heart rate. A urine test and a swab of the vagina may be taken to look for infection. Based on these results, your provider will decide whether you are in true preterm labor and what treatment is appropriate.
Frequently Asked Questions
Can early labor be stopped at home?
No. There is no proven home treatment to stop early labor. Resting, drinking water, or emptying your bladder will not reverse cervical changes. You need a medical evaluation to determine if labor can be delayed.
What medications stop preterm labor?
The most common medications are tocolytics such as nifedipine, terbutaline, and magnesium sulfate. These can slow or stop contractions temporarily, but they are not a cure. Corticosteroids (betamethasone or dexamethasone) are given to speed up the baby’s lung development.
How long can doctors delay preterm delivery?
Treatment can often delay delivery by 48 hours to several days. That time is critical for steroids to take effect and for the mother to be moved to a hospital with a NICU. In some cases, labor can be stopped for a few weeks, but that is less common.
