1. A tampon wetness detection system comprising:

  • (a) a housing having a distal end and a proximal end, said proximal end being shaped and dimensioned for insertion into a distal end of an absorbent body insertable into a vagina, said proximal end of said housing being fluid permeable;

    (b) a radio frequency identification device being implemented in said housing, said radio frequency identification device including a transmitter;

    (c) a conductive wetness sensor being in said proximal end of said housing and in electrical communication with said radio frequency identification device, such that when said conductive wetness sensor senses wetness said radio frequency identification device is operable, said conductive wetness sensor including two metal plates and an absorbent substance disposed therebetween, such that when said absorbent substance becomes wet, said sensor becomes conductive; and

    (d) a remote reporting device including a receiver for receiving a radio signal concerning the wetness of the absorbent body from said radio frequency identification device and further including a reporting mechanism for reporting a user of the wetness of the absorbent body.
