Abstract: A sanitary pad for tween girls for use under a swimsuit. The sanitary pad includes a body having a size and shape conforming to a genital area of an average tween girl and is inconspicuous while being worn by the tween under her swimsuit. The body has a waterproof outer layer, an inner lining and a peripheral edge. The waterproof outer layer has a removable backing covering an adhesive such that upon removal of the backing, the body is removably adherably positionable in the swimsuit and remains in place during vigorous swimming activities and play, whether in or out of the water. The inner lining is capable of absorbing menstrual fluid. A vaginal plug is positioned on the inner lining so as to align comfortably at the opening of the tween's vagina.
