The current invention in some embodiments thereof relates to a sanitary pad which has a flat configuration for easy storage and transport and folds to form a 3D shape including a bulge for dividing between skin in a sensitive area. In some embodiments, in the bulge may be perpendicular to a flat portion of the pad. Optionally, the fin may have a triangular shape. For example, a menstrual pad may include an anterior flat area configured to lie against the vagina and/or absorb menstrual fluids and a posterior bulge configured to fit into an intergluteal cleft. For example, the bulge may have the form of a triangular fin. Optionally, the pad is reformed from the flat configuration to its 3D configuration by folding a posterior portion of the pad.
