Here are some signs that you may have preterm labor:
Call your health care provider or go to the hospital right away if you think you're having preterm labor, or if you have any of the warning signs. Call even if you have only one sign.
Your health care provider may tell you to:
If the signs get worse or don’t go away after 1 hour, call your provider again or go to the hospital. If they get better, relax for the rest of the day.
Your provider may give you medicine to try to stop preterm labor. You also may get some medicine that can improve your baby's health, even if he does come early.

No one knows for sure what causes a woman to have preterm labor. But if you have certain risk factors, you're more likely than a woman without risk factors to have preterm labor. Risk factors include: having already had a premature baby or getting pregnant again too soon after having a baby; being pregnant with twins or more; and having problems with your uterus or cervix. You're more likely to have preterm labor if you're underweight or overweight or if you have health problems, like high blood pressure, diabetes or certain infections. Things in your life like stress, smoking, drinking alcohol and using drugs also put you at risk. Talk to your provider if you have any of these risk factors. You may be able to reduce your risk and have a better chance for a healthy pregnancy.

If you think you're in labor, call your health care provider, no matter what time of day or night.
There is no set timeline for survival for babies born early. Babies born earlier than 23 weeks have a much smaller chance of survival than babies born after 23 weeks.
About 9 out of 10 babies born at 28 weeks survive. But many have serious health problems. Any baby born before 37 completed weeks of pregnancy is considered premature. Premature babies have less time to develop in the womb than babies who arrive on time. This puts them at greater risk of medical and developmental problems. Every extra day in the womb helps the baby develop and mature and probably improve his or her health and development later in life. Between 23 and 26 weeks, every extra day in the womb increases a baby's chance of survival by 2 to 4 percent.
