Final answer:
The signs of premature rupture of membranes (PROM) include fluid leakage, increased fetal movement, and abdominal cramping.
Step-by-step explanation:
Prominent signs or symptoms of premature rupture of membranes (PROM) include fluid leakage from the vagina. This can be described as a sudden gush of fluid or a continuous trickle. Other symptoms that may accompany PROM include increased fetal movement and abdominal cramping. Back pain, on the other hand, is not typically associated with PROM.
