The cause is not always known. Sometimes it is caused by preterm premature rupture of membranes (PPROM). This is when the amniotic sac breaks before 37 weeks and labor has not started within 1 hour.

This problem is more common in women who:
- Are Black
- Are pregnant with more than one baby
- Used assistive reproductive technology to become pregnant
- Are under the age of 16 years old
Some things that may raise the risk are:
- Prior premature birth
- Problems with the cervix
- Certain infections
- Substance use
- Alcohol use
- Mental health problems, such as depression or anxiety
- Problems with the placenta or uterus
- Vaginal bleeding
- Birth defects in the fetus
Problems may be:
- Belly cramps with or without diarrhea
- Watery or bloody vaginal discharge
- An increase in discharge
- Dull pain in the lower back
- Pressure in the pelvis and tightening in the thighs
Treatment will depend on the baby's growth, especially the lungs. Labor may be allowed to go on in a baby that is more developed. The doctor may try to stop labor in a baby that is not developed enough.
Some ways this may be treated are with:
- Tocolytics to try to delay labor for a few days
- Corticosteroids to help the baby's lungs grow
- Antibiotics to treat an infection
