Your baby lies in an amniotic sac of fluid sometimes referred to as 'waters'. If your waters break before labour begins it is called premature rupture of membranes (PROM). If PROM occurs before your baby has reached full term the medical term is preterm premature rupture of membranes or PPROM. This is when the membrane sac and the amniotic fluid break before the onset of labour and before 37 weeks of pregnancy.
PPROM occurs in around 2% of pregnancies but is associated with 40% of preterm deliveries.
Sometimes women mistake the leaking of amniotic fluid for urine, especially when it leaks slowly. If you notice any symptoms or think your membranes may have ruptured call your primary health care provider immediately.
