Symptoms of preterm labor can happen any time before the 37th week of pregnancy. It can be hard to tell preterm contractions from normal labor, pregnancy, aches, or baby movements.
Problems may be:
- Contractions that do not stop
- Watery discharge from the vagina
- Spotting or bleeding
- Pressure on the pelvis that feels as if the baby is pushing down
- A low, dull backache
- Cramps that come and go and may happen with diarrhea
