Symptoms of Preterm Labor and Delivery

Symptoms of preterm labor can occur anytime before your 37th week of pregnancy. Preterm labor contractions may or may not feel different from normal labor contractions. In many cases, it is hard to tell the difference between preterm contractions and normal aches or baby movements. Talk with your doctor about the signs of preterm labor.

The signs and symptoms of preterm labor include:

  • Contractions every 10 minutes or more
  • Watery discharge from your vagina
  • Light vaginal spotting or bleeding
  • Pressure on your pelvis that feels as if your baby is pushing down
  • Low, dull backache
  • Menstrual-like cramps that come and go
  • Abdominal cramps that may occur with diarrhea

Call your doctor if you experience any of these symptoms or any unusual sensations.
