Position the menstrual cup inside the vaginal canal

Before the period, fold the menstrual cup using the preferred method and insert it into the vagina with the folded side first.

It should sit up below the cervix in the vaginal canal but not right against the cervix.

The cervix will stop the cup from going anywhere other than the vaginal canal. If the cup sits too high, one might experience leakage. The stem should be entirely inside the vagina.
