The vaginal fornix is the widened area just below the cervix, and its size is similar in most women. The Mimas β disc is designed to fit this space. However, a low cervix position can narrow the fornix, making the smaller Mimas α disc a better option for those with a low cervix.
The disc stays securely in place by tucking it behind and above the pubic bone, providing invisible protection without relying on suction.
