This is a Prospective open-label, comparative pivotal study with comparison of self-assessments with blinded investigator assessments. Pregnant women attending the labor and delivery unit of the hospital or emergency clinic and reporting unidentified wetness (undetermined whether this is amniotic fluid leakage or urinary incontinence) will be enrolled in this study. After informed consent is obtained, each subject will be given a single AL-SENSE to use up to 12 hours or until the perception of wetness.
