The woman inserts a ring into her vagina each month. The ring is soft and flexible, so it can be flattened and inserted easily through the vaginal opening. It should be inserted high into the vagina, and it should not feel uncomfortable once it is in place.
The ring is removed after 21 days, and following a 7 day break a new ring is inserted. You can get some bleeding, like a light period, during your ring-free break. Ensure your hands are clean before inserting or removing the ring.
