Pregnancy is a journey filled with excitement, anticipation, and sometimes a bit of panic (Did I just feel a contraction?). One of the biggest concerns for expecting moms is preterm labor —when labor starts before 37 weeks of pregnancy .

But here’s the good news: while preterm labor can feel scary, there are ways to reduce the risk and protect both you and your baby. This guide covers everything you need to know about preterm labor , including warning signs, treatments, prevention tips, and recommended products to help you stay as comfortable and prepared as possible.


What is preterm labor?

Preterm labor happens when contractions begin before 37 weeks of pregnancy—about three or more weeks before your due date. Since a full-term pregnancy lasts around 40 weeks, babies born too early may have difficulty breathing, feeding, and maintaining body temperature. Some may also experience long-term health challenges .


The good news? Some cases of preterm labor can be stopped or delayed, giving your baby more time to develop inside the womb.

What causes preterm labor?

Doctors don’t always know the exact cause of preterm labor, but some possible reasons include:

  • Problems in the Uterus – Bleeding, infections, or an abnormally shaped uterus.
  • Carrying Multiples – Twins, triplets, or more increase the risk.
  • Infections – Especially in the uterus, bladder, or kidneys.
  • Short Cervix – A cervix that is too short or weak to stay closed.
  • Previous Preterm Births – If you've had one before, your risk is higher.

Other lifestyle factors that might increase risk include:

  • Smoking or drug use
  • Being underweight
  • Short gaps between pregnancies (less than 6 months)
  • Chronic stress (Yep, easier said than done, but stress management is key!)

Who’s at risk for preterm labor?

While preterm labor can happen to anyone , some women are at higher risk , including:

  • Women who had a previous preterm birth
  • Women pregnant with twins or more
  • Women whose water breaks early (before 37 weeks)
  • Women with certain infections or previous cervical surgery

Important tip
If you fall into a high-risk category , talk to your doctor early about monitoring your pregnancy more closely.

Signs & symptoms of preterm labor

It can be hard to tell the difference between normal pregnancy discomfort and signs of preterm labor . Here’s what to watch for:

  • Frequent contractions – More than 6 contractions in an hour (even if they’re painless).
  • Changes in vaginal discharge – Watery, thick, or bloody discharge.
  • Pelvic pressure or lower back pain – A feeling like the baby is "pushing down."
  • Belly tightening – Like Braxton Hicks, but more intense and frequent.
  • Leaking fluid – A trickle or gush of fluid (your water breaking).
    Cramping or Diarrhea – Cramps that feel like menstrual pain.

Not sure if it’s real labor? Try resting and drinking lots of water —if the contractions don’t stop , call your doctor ASAP!

When to call your doctor

Call your doctor immediately if you experience:

  • More than 6 contractions in an hour
  • Bright red vaginal bleeding
  • Severe pain that doesn’t go away
  • Leaking or gushing fluid
  • Reduced baby movement

It’s always better to call and be safe than to wait it out.

How is preterm labor treated?

If you show signs of early labor , your doctor may try to:

1. Slow or stop contractions

Tocolytic medications – Help delay labor long enough to get additional treatments.

2. Speed up baby’s development

  • Steroids – Help develop the baby’s lungs if you’re under 34 weeks.
  • Magnesium Sulfate – Can protect the baby’s brain and reduce the risk of cerebral palsy if labor is before 32 weeks.

3. Prevent future preterm births

Progesterone therapy – Can reduce the risk by one-third for women with a history of preterm birth or a short cervix .

Can preterm labor be prevented?

While not all cases can be prevented, there are things you can do to lower your risk:

  • Take Progesterone Supplements – If recommended by your doctor.
  • Manage Chronic Conditions – Like diabetes or high blood pressure.
  • Avoid Smoking, Alcohol, & Drugs – They increase the risk.
  • Reduce Stress – Yoga, meditation, and deep breathing help.
  • Stay hydrated – Dehydration can trigger contractions!
  • Eat a Healthy Diet – Focus on protein, iron, and folate-rich foods.

Final thoughts: Staying calm & prepared

Preterm labor can be stressful , but being informed makes a huge difference . Remember:

  • Know the warning signs & call your doctor if needed .
  • Take care of yourself —hydration, nutrition, and stress management matter.
  • Follow your doctor’s advice on medications and treatments.

And most importantly...don’t panic! Many women with preterm labor symptoms still carry full term. Trust your body, stay in touch with your doctor, and take it one day at a time.
