Pads are absorbent materials that are worn in the underwear to manage menstrual flow. They come in a variety of sizes, shapes, and absorbencies to suit the different needs of women during their periods. Pads can be made of different materials, such as cotton, rayon, and synthetic fibers, and some may have additional features like wings or adhesive backings to help keep them in place. Some women prefer pads over other menstrual products, like tampons or menstrual cups, because they are easy to use, comfortable, and do not require insertion into the vagina.
