Premature Labor

Premature labor is also called preterm labor. It’s when your body starts getting ready for birth too early in your pregnancy. Labor is premature if it starts more than three weeks before your due date.

Premature labor can lead to an early birth. But the good news is that doctors can do a lot to delay an early delivery. The longer your baby gets to grow inside you -- right up to your due date -- the less likely he or she is to have problems after birth.

What Increases Your Risk

Lots of different things can increase your risk of premature labor. Some of them are:

Symptoms

To stop premature labor, you need to know the warning signs. Acting fast can make a big difference. Call your midwife or doctor right away if you have:

  • Backache, which usually will be in your lower back. This may be constant or come and go, but it won’t ease even if you change positions or do something else for comfort.
  • Contractions every 10 minutes or more often
  • Cramping in your lower abdomen or menstrual-like cramps. These can feel like gas pains that may come with diarrhea.
  • Fluid leaking from your vagina
  • Flu-like symptoms such as nausea, vomiting, or diarrhea. Call your doctor even about mild cases. If you can’t tolerate liquids for more than 8 hours, you must see your doctor.
  • Increased pressure in your pelvis or vagina
  • Increased vaginal discharge
  • Vaginal bleeding, including light bleeding

Some of these may hard to tell apart from normal symptoms of being pregnant, like backache. But you can't be too cautious. Get any possible warning signs checked out.

How to Check for Contractions

Checking for contractions is a key way of spotting early labor.

  1. Place your fingertips on your abdomen.
  2. If you feel your uterus tightening and softening, that’s a contraction.
  3. Time your contractions. Write down the time when a contraction starts, and write down the time at the start of the next contraction.
  4. Try to stop the contractions. Get off your feet. Change your position. Relax. Drink two or three glasses of water.
  5. Call your doctor or midwife if you continue to have contractions every 10 minutes or more often, if any of your symptoms get worse, or if you have pain that’s severe and doesn’t go away.

Keep in mind that many women have harmless false labor called Braxton Hicks contractions. These are usually erratic, don't get closer together, and stop when you move around or rest. They are not part of labor. If you're not sure about the type of contractions you’re feeling, get medical advice.

If You Need to Go to the Hospital

If your doctor or midwife thinks you're going into premature labor, you probably need to go to the hospital. Once you arrive, a doctor, midwife, or nurse will:

  • Ask about your medical history, including medicines you’ve been taking during pregnancy.
  • Check your pulse, blood pressure, and temperature.
  • Put a monitor on your belly to check your baby's heart rate and your contractions.
  • Swab for fetal fibronectin, which helps predict the risk of delivering early.
  • Check your cervix to see if it is opening.

If you are diagnosed with premature labor, you may need treatment, which may include:

  • IV fluids
  • Medicine to relax your uterus and stop labor
  • Medicine to speed up the development of your baby's lungs
  • Antibiotics
  • Being admitted to the hospital

If your labor has kept up and can’t be stopped, your doctor or midwife will get ready to deliver your baby.

If doctors say you’re not in premature labor, you can go home. Despite the popular belief, bed rest doesn't seem to help prevent preterm birth and has risks of its own.

What Happens if My Baby Is Born Early?

About one in 10 babies born in the U.S. are preemies. Most preemies do well as they get older and catch up to their full-term peers in time.

But these kids do have a higher risk of problems. Premature babies grow more slowly than babies born at full-term. They have a higher risk of certain long-term health problems, including autism, intellectual disabilities, cerebral palsy, lung problems, and vision and hearing loss.

The earlier a baby is born, the more likely he or she is to have problems. Babies born after 7 months usually need a short stay in the hospital’s neonatal intensive care unit (NICU.) Babies born earlier than that face much bigger risks. They will need specialized care in the NICU.
