In its preferred embodiment, the article (10) comprises a pad having an upper outer layer (26), a lower outer layer (28), and an intermediate pH responsive component. A double sided adhesive strip i s attached to the lower outer layer (28). The upper outer layer (26) is compos ed of a liquid permeable material. Intermediate of the upper outer layer (26), and the inner outer layer is a pH sensitive component. The intermediate laye r is a pH sensitive material, and may be one of a variety of such in the presence of an alkaline fluid, such as amniotic fluid. The pH sensitive material responds by turning to a purple blue color. The change in color act s as a visual indicator to the wearer of the possible presence of amniotic flu id outside of the amniotic sac.
