Menstrual pads are probably the most popular alternative to tampons. These are worn in the underwear to collect a woman's menstrual flow as it leaves her body, and disposable and reusable versions are available. Interlabial pads are other types of menstrual pads worn sandwiched between the labia. Menstrual cups can also be inserted into the vagina during a woman's period to help collect the flow of menstrual blood. Some women also use natural sea sponges as an alternative to tampons.
Unlike tampons, which collect menstrual blood inside the vagina, menstrual pads collect the blood as it leaves the body. The menstrual blood is drawn into a very absorbent cloth-like material, and a thin protective plastic layer helps protect the underwear. Some menstrual pads also have tabs, known as wings, that wrap around the sides of the underwear to help prevent stains in these areas. This alternative to tampons, also referred to as a sanitary napkin, is typically attached to a woman's underwear during her period.
