The main difference between a female sanitary napkin pad and a women's panty liner underwear. The panty shields small and thin. Menstrual blood can easily leak on the pants. The female panty napkin linear can be used every day. Sanitary napkins are generally larger and are used during menstruation. Even mini sanitary napkins are only reduced in size, but they can absorb more menstrual blood than pads. The pad can be used in normal times when there is more vaginal discharge. Use sanitary napkins for more menstrual flow and sanitary pads for less menstrual flow.
