Menstrual Cup – Why A Menstrual Cup Is WAY Better Than Tampons

Information in this article has been provided by Mooncup menstrual cups.

What Is A Menstrual Cup?

The Mooncup is a reusable menstrual cup, made from a soft, silicon rubber and is around two inches long. It is worn internally like a tampon but collects menstrual fluid rather than absorbing. Unlike tampons, a menstrual cup is not a disposable product, so you only need to buy one.

How Much Fluid Can A Menstrual Cup Contain?

The Mooncup will hold 30ml of fluid, which is roughly one third of the average total produced each period. A light seal is formed with your vaginal walls allowing your menstrual fluid to pass into the cup without leakage or odour. You will probably find that you need to empty your menstrual cup less frequently than you currently replace towels or tampons.

Why Is A Menstrual Cup Better?

Menstrual cups are so much better for your body, the environment and your pay packet!

Menstrual cups are better for your body because:

  • Tampons absorb 65% menstrual fluid and 35% natural moisture, creating imbalances in the moisture and pH levels of the vagina. Menstrual cups do not interfere with your healthy vaginal environment
  • A menstrual cup will not deposit fibres in your vaginal wall
  • Menstrual cups have not been associated with toxic shock syndrome
  • Menstrual cups contain no bleaches, deodorisers or absorbency gels
  • Silicon menstrual cups will not cause irritation and is suitable for women with sensitive skin, thrush, eczema or allergies
  • For your safety, the Mooncup menstrual cup is made from a special medical grade non-allergic silicone. Silicone is derived from silica which is one of the most abundant minerals on earth.
  • The smooth surface of the menstrual cup allows the mucus membranes of your vaginal wall to continue their essential cleansing and protective functions. The menstrual cup does not absorb your body’s natural defence mechanisms.

Menstrual cups are better for the environment and your pay packet because:

  • Imagine the towels and tampons that you will be buying and disposing of in landfill sites during those years! The average woman throws away 125 to 150kg of tampons, pads and applicators in her lifetime. Unlike pads and tampons, menstrual cups are reusable, eliminating the need to carry bulky spares. With proper care your Mooncup will last for several years.

How Easy Is It To Use A Menstrual Cup?

Correctly inserted, the Mooncup is so comfortable that you will forget it exists. It may take a little practice at first as you need to find the angle and position that is right for you.

Once you have perfected it you will be amazed at how simple a menstrual cup is to use. You will need to empty, rinse or wipe and reinsert your menstrual cup every four to eight hours depending on your flow. The fluid remains inside the cup, and the process is not messy or uncomfortable.

A menstrual cup can safely be used overnight and is great for all sports, swimming and travelling. It can be cleaned in the same way as baby equipment: with sterilising fluid, or by boiling for five minutes in an open pan of water.

“I LOVE my Mooncup! I found it quick, convenient and easy to use (I think the trick is definitely to aim towards the small of the back when inserting) and comfortable to wear. I’M FREE! I’M FREE! It doesn’t leak or smell and I don’t go to the loo and then think “damn I should’ve brought a tampax in with me” or get up in the morning and think “now I must fill my pockets with tampax” if I’m going out! The great thing is, once you’ve got it in, you’ve got it with you! Love it! Thanks! More women should know about this…”

How Do You Use The Mooncup?

  • Find a comfortable sitting, standing, squatting or kneeling position. Relax and take your time.
  • Press the sides of the menstrual cup together and then fold in half again.
  • Hold the folded sides firmly together between thumb and forefinger of one hand. The single curved edge should be away from your palm.
  • Stay relaxed. With your free hand gently separate the labia and push the curved edge of the folded menstrual cup up into the vagina.
  • Insert the menstrual cup fully following the natural angle of your vagina. Aim towards the small of your back, not the top of your head. You do not need to push the menstrual cup up high into the vagina, the vaginal muscle will keep it in place.
  • Once the menstrual cup is fully inserted grasp the base of the cup, not the stem, and rotate it once to ensure that it has fully unfolded.

Most women find that the stem is too long. You will need to remove the menstrual cup and cut the stem to your own requirements.

It is important to keep your menstrual cup clean, so wash it regularly with mild soap and hot and water. It can be cleaned more thoroughly between periods.

Menstrual Cup FAQ’s

Here are the most commonly asked questions about menstrual cups.

Q. Can you use a menstrual cup in public toilets?

A. Yes, you can still use your menstrual cup in public toilets. Simply take a small bottle of water into the toilet with you and rinse it with this. Alternatively you
can wipe with toilet paper and give your menstrual cup a thorough clean at a more convenient time.

Q. My flow is very light and I find tampons extremely painful to remove. Is it okay to use a menstrual cup with a light flow?

A. Yes it is fine to use a menstrual cup when your flow is light. Menstrual cups are not absorbent and will not cause dryness so you will find removal much more comfortable than with tampons.

Q. My menstrual cup is leaking, what can I do?

A. The most common reason for leakage is not placing the menstrual cup low enough in your vagina. The menstrual cup needs to be placed just inside the entrance to your vagina, not up near the cervix where tampons are placed.

Also, you need to check that the whole of the stem is fully inside you. Most women need to trim the stem. If you think you need to trim the stem, remove your menstrual cup and cut the end with scissors. Trim a little off at a time and reinsert your menstrual cup to check how it sits. Repeat this process until it is fully inside you and is comfortable.

Another reason for leakage is due to poor seal formation with your vaginal wall. You can try twisting and rotating the menstrual cup once inserted. You can also try pulling the menstrual cup down slightly and then gently pushing it inward. Clamping your pelvic floor muscles around the menstrual cup will also help to create a good seal.

Occasionally leakage can occur because the small holes below the rim of the Mooncup have become blocked. Use a clean pin and remove any debris blocking the holes. Sterilise your menstrual cup and re-insert.

Finally, leakage may be due to the size you are using not being a good fit. In this case please contact the Mooncup advice service.

    1. Menstrual cups will not come out if you cough or sneeze. I recommend them, menstrual cups are life-changing. There are many brands, most are online. I recommend that you find your cervix and go from there. The Lily Cup is great. There is a compact style that folds into itself so it is very discreet and easy to carry. The original is rather long, but it works great for most people if you cut the stem off. The Lunette is also great.
