New to menstrual discs and cups?

First, determine the proper fit

Lumma™ is proud to be the only company in the world that offers three sizes of menstrual discs.
For optimal sizing, compare the length of your finger to a ruler before measuring, noting which portion of your finger measures 1½ inches (typically from the tip to the 1st knuckle) and 2½ inches (typically from the tip to the 2nd knuckle).

Sanitize your hands and find a comfortable position.
Insert your index or middle finger into your vagina and extend it as far it will go.
Your cervix is located right where your finger stops. It should feel soft but firm and rigid, almost like the tip of your nose.

Since your cervix can change positions during your period, we offer a free cup or disc with each purchase. We recommend getting two sizes to help keep you covered year-round.

Disc

Which size disc is right 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

INSERTION:

1
Squeeze the rim in the middle of the menstrual disc to form an “8” shape, maintaining the string in front of the disc.
2
Insert the disc into the vaginal canal.
3
Continue pushing the disc toward the end of the canal until you feel that it’s positioned under your cervix.
4
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.

Cup

Which size cup is right for you?

Most menstrual cup manufacturers only offer one size. We offer ten, because all of our customers are unique, and so are their periods. Let's take you through it.

Sizing guide:

H = high cervix

M = medium cervix

s = short cervix

SB Has given natural childbirth

*Cups for those who have given natural childbirth are 0.4 inches (1 cm) wider than their counterparts.

How to use your cup

1
Sanitize your hands and find a comfortable position.
2
Fold the cup tightly, with one narrow end.
3
Once the disc enters the vaginal canal, the rim of the cup will pop open and begin to create suction, forming a seal.

REMOVAL: Each cup features a patented petal shape to help you position your fingers properly for removal. Once you've gripped the cup, squeeze until you feel the suction release. Once deflated, it can be removed easily.

Sterilizing your Lumma products

Simply boil in water for three minutes. Your disc or cup will be sterile, clean, and good to go.
