Abstract
There is provided a tampon that comprises an absorbent pledget and a menstrual fluid indicator associated therewith. The absorbent pledget has a proximal end that is placed near the cervical bone and a distal end opposite the proximal end. The indicator is preferably an additional layer formed and in contact with the entire circumference of the absorbent pledget, and is located near the distal end. The indicator is designed to provide a sensory signal to the user that the capacity of the absorbent pledget of the tampon is exhausted, or just before by-pass leakage commences.
