Abstract
Abstract A sanitary napkin includes an elongated forward portion, an elongated rearward portion, and an enlarged intermediate portion therebetween. The forward portion is longer than the rearward portion, and will extend forwardly beyond the vaginal area of the user. The enlarged intermediate portion will be located between the vaginal area and the anal area so as to absorb any discharge flowing along the body when in a reclined position. Adhesive strips on the sanitary napkin will allow the napkin to be removably fastened to the user's undergarments.
