Before you start using your menstrual cup for the first time, and at the beginning of each period, boil the cup for 10 minutes in a generous amount of water. Also remember to carefully wash your hands with soap every time you are about to handle the cup.
Fold the cup into a tight package to make inserting it in the vagina as easy as possible. The most common folding techniques include the so-called heart-, shell-, and triangle-shaped folds. You are sure to find the folding technique that suits you best.
Do not hesitate to try different techniques, and do not feel discouraged if you do not succeed right away.
First, check that the air holes at the top of the cup are open. Then, relax your mind and body. The most common positions to insert the menstrual cup into place are sitting on the toilet, squatting slightly, or one foot lifted on top of the toilet seat. Especially at the beginning, you can facilitate the insertion with, e.g., water or a water-based lubricant.
Hold the cup so that it is tightly folded, and insert it (rim first) fully into the vagina. When the cup has unfolded completely, the base feels somewhat round. If the cup has not unfolded completely, pinch the base of the cup and turn the cup, e.g., 180 degrees. You can also pull the cup slightly downwards by the stem, turn the cup, and push it back into place.
The stem of the cup must not remain outside the vagina. If the stem feels uncomfortable, you can shorten it or remove it completely by cutting it with scissors. If you cut the stem, be careful not to damage the base of the cup.
When the cup has been inserted into place correctly, you should not be able to feel it at all.
The emptying interval of the cup depends on the amount of menstrual flow. On days when the flow is heavy, you may have to empty the cup 2–4 times. It is, however, quite possible that you only have to empty the cup in the mornings and evenings. Do, however, empty the cup at least every 12 hours.
Remember to remain relaxed when removing the cup. You may either sit on the toilet, lift your foot on top of the toilet seat, or squat. When you are ready, insert your fingers into the vagina and squeeze the base of the cup. You can also slide your fingers up the side of the cup, so that the cup folds and the vacuum inside the cup is released.
Then, push the cup towards the vaginal opening with your pelvic floor muscles the same way you do when you are doing your business in the toilet. Use your fingers to guide the cup on its way out of the vagina. At this point, pulling the cup down by its stem is not a good idea, as it intensifies the vacuum inside the cup and makes the cup stay more tightly in its place.
Empty the cup into the toilet bowl or sink and rinse it. It is advisable to start rinsing the cup under cold water, as it protects the cup from discolouration. When rinsing the cup, you may also use mild oil-free soap with a pH value of 3.5–5. If there is no sink in the toilet facilities, you can also wipe the cup with toilet paper or a wet wipe intended for the intimate area.
Check in connection with the cleaning that the air holes at the top of the cup are clean and completely open.
When your period has ended, disinfect the cup by boiling it for 10 minutes in a generous amount of water or wash it with antiseptic fluid. Let the cup dry so that it remains properly aerated and then slip the cup in the supplied breathable cotton bag. The bag protects your cup, and it is easy to carry around when your period is about to start.
If you wish, you can also insert the cup in place in advance around the time when your period is expected to start. Unlike tampons, the cup does not dry the sensitive vaginal lining and thus irritate your body.
