Symptoms of preterm labor

If you think you’re having preterm labor, get medical help right away. Contractions alone don’t mean you’re in preterm labor. What matters more are changes in your cervix. The cervix is the opening at the lower end of the uterus. Symptoms of preterm labor include:

• 4 or more contractions per hour

• Strong contractions

• Constant menstrual-like cramping

• Low-back pain

• Mucous or bloody fluid from the vagina

• Bleeding or spotting in the second or third trimester

Evaluating preterm labor

Your healthcare provider will try to find out if you’re in preterm labor or just having contractions. They may watch you for a few hours. You may have the following tests or procedures:

• Pelvic exam. This is to see if your cervix has effaced (thinned) and dilated (opened).

• Uterine activity monitoring. This is used to detect contractions.

• Fetal monitoring. This is done to check the health of your baby.

• Ultrasound. This test looks at your baby’s size and position.

• Amniocentesis. This test checks how mature your baby’s lungs are.

Caring for yourself at home

If you have preterm contractions but your cervix is still thick and closed, your healthcare provider may tell you to:

• Drink plenty of water.

• Do fewer activities.

• Rest in bed on your side.

• Don't have intercourse or stimulate your nipples.

When to call your healthcare provider

Call your healthcare provider if you have any of these:

• 4 or more contractions per hour

• Bag of water breaks

• Bleeding or spotting

If you need hospital care

Preterm labor often means that you need hospital care. You may need complete bed rest. You may have an IV (intravenous) line in your arm or hand. This is to give you fluids. You may be given pills or injections. These are done to help prevent contractions. You may get a medicine called a corticosteroid. This is to help your baby’s lungs mature more quickly.

Are you at risk?

Any pregnant woman can have preterm labor. It may start for no reason. But these risk factors can increase your chances:

• Past preterm labor or early birth

• Smoking, drug, or alcohol use in pregnancy

• A multiple pregnancy (twins or more)

• Problems with the shape of the uterus

• Bleeding during the pregnancy

The dangers of preterm birth

A baby born too soon may have health problems. This is because the baby didn’t have enough time to grow. Some of the risks for your baby include:

• Not breastfeeding or feeding well

• Having immature lungs

• Bleeding in the brain

• Death

Reaching term

Your goal is to get as close to term (week 37 or later) as you can before giving birth. The closer you get to term, the higher your chance of having a healthy baby. Work with your healthcare provider. Together, you can take steps that may keep you from giving birth too early.
