Menstrual Cup Dangers
If you’ve got a vivid imagination or are prone to compulsive searches of the internet for any negative product reviews, you may have been put off by the idea of using period cups by some of the stories you’ve read. We’d like to set the record straight and, hopefully, put your mind at rest.
Frequently asked questions
Can I get a get an infection from a menstrual cup?
It’s extremely rare to pick up an infection from the cup itself. If anything, you’re more likely to introduce bacteria from your hands. That’s why it’s so important that you wash your hands thoroughly every time you insert or remove the cup and you sterilize the menstrual cup before using it. Read more about How to Clean Your Menstrual Cup. If you’re out and about, and you only have water and/or scented soap to clean your period cup, only use the water. You can use a menstrual cup cleaner, cup wipes or unscented soap and water when you get home.
Can I get Toxic Shock Syndrome (TSS) from a period cup?
TSS is a fairly rare bacterial infection that’s associated with (but not exclusive to) tampon use. In particular, tampons being left inside the vagina for long periods). Although there have only been two cases of TSS in connection with menstrual cup use, we recommend you limit the length of time you keep your cup inside you to 12 hours (even if your flow is very light). Even better, empty it 2-4 times a day. Read more about Toxic Shock Syndrome.
Is it dangerous to sleep with my menstrual cup in?
Not at all. One of the great things about period cups is that you can sleep soundly without having to wake up to change your pad or tampon.
Is it OK to use a menstrual cup with an IUD?
Yes, absolutely. Although there are some things you need to be aware of. Check out our article ‘Using a Menstrual Cup with an IUD’ for more information.
What if I want a poo when I’ve got the cup inside me?
Simple. You have a poo, just as you would without the cup. Just remember to wash your hands before and after you go to the toilet, in case you need to check the cup is still sitting correctly.
Do I have to avoid swimming?
No. On the contrary. Menstrual cups are ideal for swimming as everything’s inside and you don’t have to worry about any strings making an unwelcome appearance.

Hi Katyayani!
Most users are anatomically capable of using either size Lunette, but one may be a more comfortable fit over the other. We believe that the most important factor when choosing the size is the amount of flow. Size 1 is smaller and softer. It is best for light flow and good cup for beginners. Size 2 is made of firmer silicone than size 1. It is suitable for heavy flow because it is bigger and holds more liquid than size 1.
Have you checked your cervix? If you can barely reach it or can’t reach it at all your cervix is high. If you’re able to reach it easily, it is low. With a high cervix you can use both sizes but with a lower one I’d recommend purchasing size 1 since it is shorter than size 2.
Menstrual flow varies during periods and on a heavier day you will need to empty the cup more often than on lighter days, no matter which size it is.
There are many factors that can affect the cup size, but the flow is the most important. Other factors can be age, location of the cervix and sensitive bladder – these can also be key issues when choosing the size.
For washing your hands you can use regular soap. Just make sure to thoroughly rinse your hands so that no foam is left on your hand and fingers.
We however do not advise using regular soap (or shower gel, detergent, etc.) for your menstrual cup. These products are not good for many reasons: their pH is normally not optimal, they can contain oils which is super bad for the cup and they can leave some remains and residues on the cup, which can irritate the vagina and/or cause damage to the menstrual cup. Perfumed soaps with unknown pH values might coat the cup with a layer of irritants that could damage the precious mucous membrane of the vagina. Some of these soaps may also contain agents that might damage the silicone.

hi im 37 yrs i have two c-section for the first 3days i wil have heavy flow which type cup should i use and im a working women if i dnt have unscented soap to wash my hands how should i wash hands n cup.
Hi Marta! Sorry to hear your Cup has been causing you discomfort! The larger size Model 2 Lunette Cup will not be doing damage to your vagina, but you might benefit from switching to the smaller Model 1 Cup. 😊 The Model 1 is made out of softer material and is a bit shorter. If you have a low cervix or bladder sensitivity the Model 1 is recommended. Please don’t hesitate to contact us at info@lunette.com so our Menstrual Mentors can offer more troubleshooting! 💙

Hi! I’ve been using lunette cup for almost 18months now but have just realised I was probably using the wrong size (that’s the reason why sometimes it felt quite uncomfortable and annoying). I’m 28 and never given birth but I haven’t been using your smaller size, infact I think I’ve been using cup B. Would have this created any problem in my cervix or vagina? I have to say, I haven’t been in any pain or anything, I only got diagnosed of polycystic ovaries over these 18 months but I wouldn’t say this was the reason?
Thanks for your answer and time 😊

My period started when I was in fifth grade (now I go to my first year (freshman) and I just got a menstural cup today. I have been looking information about menstural cup. But one thing I forgot was that I need to wash my hands and that I need to be on my menstural cycle while certing the cup in. Does anyone know if this can be dangerous.
Any help would be amazing, thank you!
Hi, Megh! It can be a bit uncomfortable if you’re poking around the vagina for a longer period of time, but it’s not dangerous if you’re being gentle. :) If you experience pain when the cup is in you should remove it immediately. Don’t hesitate to reach out to us at info@lunette.com if there’s anything we can help with!

Is it harmful if give several attempts while fixing your menstrual cup and in the end u failed to do it so. Does vagina feel stressed ?or it’s just a mind thing? I’m on my periods and 1st day I was able to insert the cup but today I’m not. And now I’m feeling as if I harmed her!
Hi Rosanne,
Great question! It really comes down to getting to know your flow a bit more intimately with a menstrual cup than you would with a tampon or pads. One of our amazing Menstrual Mentors will be happy to answer any and all questions and offer more guidance if you reach out at info@lunette.com! :)

If I naturally have quite a heavy flow, how can I tell when the cup is full?
Hi SREYASREE,
Please discontinue use of the cup immediately if you suspect the numbness is related to the menstrual cup and consult a physician. Please also reach out to us at info@lunette.com if you suspect the numbness is related to your menstrual cup so that we can investigate the matter.
Best,
Team Lunette
I started using menstural cup since yesterday. Now have numbness on my right leg fingers… Is the numbness is since yesterday I am feeling numbness…is it because of my menstural cup? …plz reply….
Can you use the cup with bacterial vaginosis?
Hi Naira!
No need to worry about this. The blood is flowing out of pin-sized opening in the cervix and the menstrual cup can’t get into the womb through this opening (and neither can a tampon).
Best regards,
Team Lunette
Do it moves inside body in vagina, by any chance? I have a fear that it may move inside body and remain their for lifetime unless done surgery?
Great question, Raji Karthick!
Urinary tract infections are typically caused from bacteria getting into the urinary tract. This can happen in a number of ways.
That being said, you want to make sure you’re always thoroughly washing your hands prior to inserting or removing your cup to avoid introducing bacteria into the urethra.
Please don’t hesitate to reach out to us at info@lunette.com if you have any other questions!
Is there any possibility of getting urinary infection when we use menstrual cups
This is a great question, Mandavi.
But don’t worry, your blood is not going to flow back into your uterus through the pin-sized cervix. Instead the blood will collect in your menstrual cup until it is emptied. If the cup becomes full before it’s emptied, you’ll notice that it’s time to empty it.
Please don’t hesitate to reach out to us at info@lunette.com with any other questions you may have!
When we lie down does blood goes back into the uterus ?if yes please tell me it cause any harm or if no ,how it remain intact to the cup.p lease reply it is confusing me alot.
Hey Maddie Knox,
Great question!
Your Lunette Menstrual Cup can be worn for up to 12 hours straight, depending on how heavy your flow is. Once removed, you’ll want to properly clean your cup before reinserting it.
For more information on how to take care of your cup, please read our blog article: How to Clean Your Lunette Cup <3
After I take my cup out and clean it, mind you this being after 12 hours, can I put it back in immediately? is the 12-hour rule for the total time in a day?
