Menstrual products are items designed to absorb or collect menstrual fluid during a woman's monthly cycle. Common types include sanitary pads, tampons, and menstrual cups. Sanitary pads are worn outside the body and stick to underwear, while tampons are inserted into the vagina. Menstrual cups are reusable silicone or rubber cups that collect fluid. These products come in various sizes and absorbencies to accommodate different flow levels. Some women also use period underwear, which is designed to be worn alone or as backup protection. Choosing the right product depends on personal preference, comfort, and lifestyle needs.
