The purpose of this study is to compare the reliability and validity of a new device with standard methods for diagnosing between amniotic fluid leakage due to premature rupture of the membranes (PROM) and urine.

Pregnant women sensing wetness and arriving to the delivery room with suspect PROM will use a self-testing device to test whether the wetness is caused by amniotic fluid leakage or urinary incontinence. Clinical evaluation will be performed to all pregnant women using standard clinical tests. The results of the standard clinical tests will be compared to the women's reading of the self-testing device results. Sensitivity and specificity of the device evaluation will be calculated.

Inclusion Criteria:

1. Pregnant women age 18 years and older attending delivery room.
2. Stage of gestation: pregnancy between 16 and 42 weeks of gestation.
3. Able and willing to read and sign an informed consent document.

3. Vaginal bleeding or spotting or excess abnormal vaginal discharge within the past 24 hours.
4. Sexual intercourse within the past 24 hours.
5. Confirmed diagnosis of any vaginal infection within the past 7 days.
6. Use of vaginal products or antibiotic treatments that reduce bacterial population or use of medications such as tamoxifen that reduce estrogen levels or antihistamines that dry mucous membranes within the past 7 days..
