Preterm premature rupture of membranes (PPROM) is when the amniotic sac breaks before 37 weeks of pregnancy and labor has not started within 1 hour. The sac holds amniotic fluid and the growing baby. In PPROM, the fluid in the sac leaks or gushes out of the birth canal. This is also known as your water breaking.

The doctor may admit you to the hospital for bed rest and to monitor you and your baby. 24 weeks is about the youngest a baby can be born. The doctor will talk to you about the risks and benefits of your options.
There is no way to prevent PPROM.
