New to menstrual discs?

First, determine the proper fit.

Lumma™ is proud to be the only company in the world to offer three sizes of menstrual discs.
To get the ideal size, compare the finger length with a ruler before measuring, noting which part of the finger measures 3.8cm (typically from tip to first joint) and 5cm (typically from tip to second joint).

Clean your hands and find a comfortable position.
Insert your index or middle finger into your vagina and take it as far as you can.
Your cervix is located exactly where your finger stops. You should feel something soft, but firm and stiff, almost like the tip of your nose.


What is the right size for you?

Short If you feel your cervix with your 1st knuckle inserted (up to 1½ in / 4 cm), you have a short cervix.
Medium 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.
High If your cervix is more than 2½ inches away, you have a high cervix.

How to use your disc

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.

REMOVAL: 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.
NOTE: The string can be shortened with scissors or, for those who prefer not to use a string, it can be cut off altogether.


What is the right size for you?

Most menstrual cup manufacturers only offer one size.
We offer ten sizes because all of our clients are unique, as are their periods.
We will help you with the choice.

How to use your menstrual cup

Clean your hands and find a comfortable position
Bend the cup tightly, making the tip narrow
As soon as the disc enters the birth canal, the rim of the cup will open and start to create suction, forming a seal

REMOVAL: Each cup has a patented petal shape to help you position your fingers properly for removal. After holding the cup, squeeze until you feel the suction release. Once deflated, you can easily remove it.
