Menstrual cup seals to the vaginal wall once inserted just below the cervix. It collects the menstrual blood and is emptied, rinsed clean, and reinserted during a woman’s menstrual cycle. Those who use menstrual cups are generally able to go 10 to 12 hour without needing to empty it. If the cup is correctly inserted, it should protect against any leaks and those using one should not experience any type of discomfort. When these types of cups were first created in the 1930s they were made of rubber material, but they were far from successful.
