If you feel your cervix with your 1st knuckle inserted (up to 1½ in / 4 cm), you have a short cervix.
If you can only feel your cervix after inserting 2 knuckles (between 1½ in / 4 cm and 2½ in / 6 cm), you have a medium cervix.
If your cervix is more than 2½ inches away, you have a high cervix.
Squeeze the rim in the middle of the menstrual disc to form an “8” shape, maintaining the string in front of the disc.
Insert the disc into the vaginal canal.
Continue pushing the disc toward the end of the canal until you feel that it’s positioned under your cervix.
Push upwards on the front of the rim, securing it behind the pubic bone. Part of the silicone string will remain outside the entrance of the vagina.
Pull lightly and slowly with the front of the string until the rim of the disc slips off the pubic bone and lines up with the entrance to the vagina, then pull out gently with your fingers.
The string can be shortened with scissors or, for those who prefer not to use a string, it can be cut off altogether.
