8 Myths About Menstrual Cups

menstrual cup, myths

There are so many myths about menstrual cups and menstruation. Does the blood flow back into the womb when the cup is full? Is it true that only those who have already given birth can use the larger cup? We put all the facts on the table and gathered the most common myths and truths.

MYTH: When the cup is full, the blood flows back into the uterus.

TRUTH: Wrong! The blood flows into the vagina and thus into the cup through the tiny hole in the cervix. It is not possible for the blood to flow back into the womb, not even if you're upside down. The muscles of the uterus push the menstrual blood out actively from the uterus.

MYTH: You can't use a menstrual cup if you have endometriosis.

TRUTH: Wrong! It is completely safe to use a menstrual cup if you have endometriosis, just ask your doctor first! 

MYTH: Virgins cannot use menstrual cups.

TRUTH: Wrong! Even people with a uterus who have not had penetrative sex can use the cup. The vagina may occur ‘narrower’ with a virgin vagina, and the hymen may still be present, but these facts do not prevent the use of the cup. At most they'll bring light challenges the first few times of inserting the cup.

MYTH: You can go pee and poo while having a menstrual cup inserted.

TRUTH: True! With the cup inserted, you can easily go to the bathroom if you make sure it's not out of place, like during a bowel movement. Good hygiene is essential so that no foreign bacteria enter the vagina or cup. If you want to make sure you're comfortable and clean, remove the cup before going to the toilet and wash your hands (and down there) carefully before inserting the clean cup. You can empty the cup as often as you'd like!

MYTH: Cup Model 1 is designed for young teens and virgins and Model 2 for those who have given birth.

TRUTH: Right and wrong! In general, the smaller menstrual cup is more comfortable and better suited for young teens and people who have not yet had sexual intercourse.

If a person who menstruates has had multiple vaginal deliveries, the cervix and the vagina can be "stretched". In that case, the larger cup is more suitable. However, the most important thing to consider in terms of choosing the right cup size for you is to know your flow! If you have a heavy flow, the larger menstrual cup is more practical because it can accommodate 5 ml more than the smaller cup. 

MYTH: The water from the toilet can be used to wash the menstrual cup.

TRUTH: No! Although water from the toilet is considered "clean", millions of bacteria live in and around the toilet seat. If you don't have access to a sink or you don't have your handy Lunette cupwipes, you can wipe the cup with clean toilet paper. At festivals or on the road the Lunette wipes are very convenient because they are biodegradable and can be thrown into the compost!

MYTH: Menstrual cups can be washed with any soap. The main thing is that it is washed.

TRUTH: Not quite. If you wash your menstrual cup with unsuitable products, you can damage the cup and your health. The pH levels of soap you should use for your cup should be at 3.5 to 5.5 because the vagina has a low pH level. Basic soaps disturb the natural acidity of the vagina. The pH level of commercial dishwashing detergents and detergents are, for example, 7-10, i.e., much higher than the value of the vagina. Also, all oily detergents are banned because they can attach themselves to the surface of the cup forming a film that gathers the smell and color of the menstrual flow in itself.

In addition, irritation of the mucous membranes of the vagina can be caused which may induce itching, burning and even inflammation. Over time, oils make the silicone material also brittle. Lunette's liquid cleanser has been developed and tested in collaboration with experts to fit perfectly to clean the silicone cup. The components of the cleanser wash the cup effectively, gently, and is safe for your body. 

MYTH: You don’t need to boil your menstrual cup after every cycle

TRUTH: Sort of. Your menstrual cup does not necessarily have to be boiled every cycle (although we highly recommend it). However, before you use your cup for the first time, make sure to boil it for 20 minutes. After your first use, boiling it for 10 minutes is good enough. Keep an eye on your menstrual cup when you boil it, you wouldn't want it to forget about it and have it burn at the bottom of the pot! Attention! Under any circumstances do not use a hand sanitizer! Try our Lunette cupwipes if you're on the go or don't have access to a sink. And don’t forget good hand hygiene!
