Menstrual Cup: Who Should Think Twice Before Using It
When something works well for most, it’s hard to talk about exceptions. The menstrual cup is safe and recommended by gynecologists as an alternative to pads or tampons, but there are conditions under which it’s advisable to wait, schedule an appointment, or look for another option for a while. Let’s review who falls into that group and what to do if you’re in that situation.
Who Should Avoid the Menstrual Cup?
There is no single study that provides an exact figure, and anyone who does so without nuance is oversimplifying. What several clinical guidelines do agree on is that it’s a minority group, primarily consisting of actual latex allergies, pelvic floor disorders, and acute phases of gynecological diseases. The rest can use it without issue, choosing the right size according to the size guide and following the user manual.
In most of these cases, the situation changes over time: an infection heals, postpartum recovery occurs, an allergy is identified and the triggering material is avoided. Only in some situations, such as a confirmed latex allergy or an untreated advanced prolapse, does the recommendation remain.
True Latex Allergy, Not Silicone
This is where terms are most often confused. True allergies to the menstrual cup, understood as an immune system response, are rare when the cup is made of medical-grade silicone: it’s an inert material and rarely causes reactions. The problem arises with latex cups, which have many more documented cases, a material that some sources indicate affects between 2% and 7% of the population to some degree.
What is more common, and often confused with an allergy, is irritation from the soap used to wash the cup, from a lubricant, or from an aggressive sterilizer. Irritation improves when changing the product that causes it; allergy persists even if you switch soaps. If you have a history of latex allergy or experience redness, itching, or swelling that doesn’t subside, it’s advisable to read this guide on menstrual cup allergy before deciding if it’s your case or just a cleaning product that doesn’t agree with you.
"I had been experiencing itching after every use for three months. I switched to a neutral, fragrance-free intimate gel and it disappeared in a week. It wasn't the cup, it was the soap."

Pelvic Floor, Prolapse, and Hypertonicity
The pelvic floor is the group of muscles that supports the bladder, uterus, and rectum, and it’s another major reason why the cup isn’t always the first option. With a pelvic organ prolapse, those muscles are already weakened and the pressure from the cup may be more noticeable or worsen the feeling of heaviness. It is not prohibited in all degrees of prolapse, but it is advisable for the decision to be made by the gynecologist or pelvic floor physiotherapist, assessing the degree and size.
On the opposite end is pelvic floor hypertonia, muscles that are too tense instead of weak. In this case, inserting it is usually painful or almost impossible, just like with tampons or during sexual intercourse. Vulvodynia and vaginismus often accompany this hypertonia, and forcing the use of the cup only adds frustration to a problem that already existed.
Endometriosis, vulvodynia, and atrophic vaginitis: it depends on the moment
Endometriosis affects, according to various estimates, at least one in ten women of childbearing age, making it a much more common reason for consultation than latex allergy. It doesn’t automatically prevent the use of a menstrual cup, but during acute pain flare-ups, when any internal pressure feels worse, many prefer to switch to pads or discs on those days and return to the cup when the pain subsides.
A similar situation occurs with atrophic vaginitis, typical of perimenopause, where the vaginal tissue becomes thinner due to decreased estrogen. Insertion may be uncomfortable not because of the cup, but due to a lack of natural lubrication. A water-based lubricant compatible with silicone usually resolves much of the issue, although in more severe cases, the gynecologist may recommend local treatment before resuming use.
| Situation | Can the cup be used? | What to do beforehand |
|---|---|---|
| Confirmed latex allergy | No with latex, yes with medical silicone | Ensure the cup is 100% medical-grade silicone |
| Pelvic organ prolapse | With medical evaluation | Consult degree and size with gynecology or physiotherapy |
| Pelvic floor hypertonia / vaginismus | With specialized support | Pelvic floor physiotherapy before forcing insertion |
| Endometriosis during pain flare-up | Better to wait on those days | Use pads or discs on those days, resume without pain |
| Recently placed IUD (less than 2-3 cycles) | Better to wait | Wait for the recommended cycles and break the vacuum when removing |
| Recovery from recent surgery or childbirth | Not until medical clearance | Wait for the postpartum or post-surgical check-up |
| Other cases, without the previous situations | Yes, without restriction | Choose the appropriate size and follow the usage manual |
Menstrual cup and IUD: the combination that requires more care
This is the case that generates the most questions in comments. The risk does not come from the cup itself, but from two mechanisms: the suction effect when removing it, which can pull on the IUD if the vacuum is not broken beforehand, and the device strings, which sometimes get trapped between the cup and the vaginal wall.
A clinical trial analysis from the scientific evidence service Preevid, part of the public health network of Murcia, found more expulsions or accidental extractions of the copper IUD among menstrual cup users, especially in the first twelve months after insertion, although the authors themselves call for higher quality trials. You can read the details in this Preevid analysis on menstrual cups and IUD expulsion.
The practical recommendation is to wait two or three cycles after the IUD insertion before using a cup, check the position of the strings from time to time, and above all, break the suction before removing the cup each time you empty it. We explain this step by step in this guide on menstrual cups with IUD, risks, and safe use. If you notice the strings are different or you can't feel them at all, consult a gynecologist before proceeding as usual.
"I had the IUD placed, and two months later I was using the cup as usual. At the six-month check-up, the IUD had moved a little, nothing serious, but since then I break the suction much more carefully before removing it."

4 signs to stop and consult before continuing to use the cup
Pain that doesn't decrease in intensity after several cycles of trying
Itching or irritation that doesn't improve with a change of soap or lubricant
IUD strings that feel shorter, longer, or that you can't find
Feeling of weight or a vaginal lump that you didn't have before
If the cup doesn't fit now, there are plenty of alternatives
Putting the cup aside for a while doesn't mean you have to go back to the old ways. The menstrual disc rests in the vaginal fornix instead of creating suction, which is why some guides mention it as an option with an IUD or certain prolapses, always with the gynecologist's approval. Menstrual underwear or pads are also still valid while you resolve whatever needs to be resolved.
And if your case is a latex allergy, the solution doesn't even involve giving up the cup: just make sure that the one you buy is 100% medical-grade silicone, without latex blends or coatings, something visible in the specifications of any menstrual cup before you decide.

Frequently asked questions about who cannot use the menstrual cup
Is it true that if you are a virgin you cannot use a menstrual cup?
No. The hymen is elastic in most cases and adapts to insertion, just like with tampons. What may happen is that the first time it may be more difficult due to unfamiliarity with the technique, not due to any physical impediment.
Does the menstrual cup worsen endometriosis?
There is no evidence that it worsens it in general. It is recommended to avoid it on days of more acute pain and to resume use without issue when the flare-up passes.
Can I use a menstrual cup if I have an IUD in place?
Yes, with precautions: wait two or three cycles after insertion, break the vacuum before removing the cup, and check the strings from time to time. It is not a prohibited combination, but it requires more care than usual use.
How do I know if I have a real allergy or just irritation?
Irritation improves when changing soap, lubricant, or sterilizer; a real allergy persists similarly and usually comes with swelling or a more pronounced rash. When in doubt, the most reliable option is dermatology or gynecology.
If the pelvic floor is weak, can the cup fall out?
It may feel lower or less secure, although it usually doesn’t "fall out" on its own. With pelvic floor weakness or prolapse, it's advisable to choose size and firmness with guidance from specialized physiotherapy, not just based on flow.
Are these situations permanent or can I try again later?
In most cases, it is temporary: an allergy is identified and the material is avoided, an infection is treated, postpartum recovery takes time. Only in more specific cases, such as advanced prolapse, does the recommendation remain, and it is advisable to review it with a gynecologist.
The menstrual cup is compatible with almost everything, but it is not a one-size-fits-all product that works for any body at any time. If you identify with any of these situations, the most honest thing is to schedule an appointment, not to force the cup. And if it’s not your case, at papayacup.com you have the entire range of sizes and firmness.
