A menstrual cup can feel unfamiliar while you are learning to insert, position and remove it, but it should not cause ongoing pain. Sharp, persistent or worsening pain is not something you should push through.
Where and when the discomfort occurs can provide useful clues. The issue may be insertion technique, the cup's length, diameter, shape or firmness, pressure on the cervix or bladder, the stem, removal technique or something unrelated to the cup itself.
Quick answer: If your menstrual cup hurts, remove it and allow the discomfort to settle. Then work out whether the pain happens during insertion, while wearing the cup, when urinating or during removal. A technique adjustment may solve the problem, but repeated pain can mean the cup is not a good fit or that another pelvic-health factor needs attention.
If you are not sure which problem sounds most like yours, use our menstrual cup troubleshooter. It checks insertion, positioning, fit, pressure, removal and stem discomfort without assuming you need to buy another cup.
Why is my menstrual cup hurting?
| What you feel | Possible cause | What to try |
|---|---|---|
| Pain or burning during insertion | Friction, vaginal dryness, an uncomfortable fold or pelvic floor tension | Stop, try again later when your pelvic floor feels less tense, use a narrower fold and consider a small amount of compatible water-based lubricant |
| Deep aching or cramping | Pressure on the cervix, cup position, cup length, shape, firmness or the cup's seal | Remove the cup, allow symptoms to settle, check your cervical position and try reinserting at a different angle before deciding whether you need a different cup |
| Bladder or bowel pressure | The cup may be too firm, too wide, a poor shape for your anatomy or incorrectly positioned | Remove the cup and consider a softer, narrower or differently shaped option if the problem repeatedly occurs |
| Stem rubbing or poking | The stem may be too long or the entire cup may sit too low | Trim the stem if the manufacturer permits it, or consider a shorter cup if the cup body itself sits too low |
| Pain during removal | The seal has not been released or the rim is being pulled through the vaginal opening while fully expanded | Release the seal first and partially fold or angle the rim as it passes through the vaginal opening |
Remove the cup first if you are in pain. Troubleshooting is easier once the discomfort has settled.
Why does my menstrual cup hurt during insertion?
Menstrual cup insertion should not require force. If insertion is painful, stop rather than repeatedly pushing the cup against tense or sore tissue.
Try a narrower menstrual cup fold
Some folds create a much smaller insertion point than others. A punch-down, seven-fold or similar narrow fold may feel easier than a wider C-fold.
There is no single “best” fold. The most useful fold is one that you can hold securely while creating a comfortable insertion point.
See our guide to different menstrual cup folds and experiment with a few options.
Aim the folded cup gently towards your tailbone rather than pushing it straight upwards. Once the cup is comfortably inside the vaginal canal, allow it to open.
Use a small amount of compatible lubricant
Friction or vaginal dryness can make insertion uncomfortable.
A small amount of water-based lubricant around the rim or insertion point may help. Avoid covering the entire cup because this can make it difficult to grip.
Check the instructions supplied with your cup before using lubricant with it.
Give your pelvic floor time to relax
Repeated attempts at insertion can cause the pelvic floor muscles to tighten, particularly if you are anticipating pain.
Try again later when your pelvic floor feels less tense. You may find it easier to sit on the toilet, squat or stand with one leg raised.
Breathe slowly and avoid holding your breath or deliberately clenching the pelvic floor.
If inserting tampons, fingers, menstrual products or having penetrative sex or cervical screening is also regularly painful or difficult, an overactive pelvic floor, vaginismus or another cause of pelvic pain may be contributing.
Do not continue forcing the cup into place.
If insertion comfort is one of your main product considerations, you can browse our period care options for insertion pain. Persistent or significant insertion pain should still be discussed with a healthcare professional rather than treated only as a product-selection problem.
Why does my menstrual cup hurt or cause cramping while I wear it?
If your cup causes a dull ache, cramping or deep internal pressure, remove it and see whether the discomfort settles.
Do not assume immediately that you simply need a smaller cup. Length, shape, diameter, firmness, position and cervical contact can all contribute.
The cup may be too long
Cervical position can affect the amount of space available for a menstrual cup.
A cup that is too long may feel crowded, press against the cervix or sit too close to the vaginal opening.
Your cervix can also move during your period, so a cup that feels comfortable on one day may feel different later in your cycle.
Read our guide to measuring your cervical position and compare the body length and total length of different cups in our menstrual cup comparison chart.
If you have a relatively low cervix, browse our period care options for a low cervix.
If your cervix is high and your main issue is reaching the cup for removal, see our high-cervix options.
The cup may be pressing against your cervix
There is no single position in which every cup must sit. A cup may naturally move higher after insertion and, for some people, the cervix may sit partly inside the cup.
This is not necessarily a problem if the cup is comfortable and leak-free.
However, direct pressure on the cervix or the way the cup sits around it may cause cramping or a deep ache for some people.
Remove the cup, allow the discomfort to settle and try reinserting it at a slightly different angle. Do not deliberately push the cup as high as possible.
The cup may be the wrong shape
Cup fit is not only about length and diameter. Shape determines where the cup is widest and how its body sits against the vaginal walls.
A cup can therefore have suitable measurements on paper but still feel uncomfortable because its profile does not suit your anatomy.
Menstrual cups can be V-shaped, bell-shaped, round or bulb-shaped, U-shaped, asymmetrical or angled or narrow-shaped.
Our Menstrual Cup Shapes Guide explains how these profiles differ.
The cup may be too firm or too wide
A firmer cup may spring open readily, but it may also feel more noticeable if you are sensitive to pressure.
A wider cup can also create discomfort even when its length is suitable.
If the cup itself feels comfortable immediately after insertion but you gradually develop bladder, bowel or pelvic pressure, compare both firmness and diameter rather than changing only one feature.

Why is my menstrual cup pressing on my bladder or bowel?
The bladder and urethra sit close to the vaginal wall, so a cup that is too firm, too wide or simply a poor shape for your anatomy may create noticeable pressure.
You may notice:
- a frequent urge to urinate
- slower urine flow
- difficulty fully emptying your bladder
- bladder or urethral discomfort
- rectal pressure
- difficulty having a bowel movement while the cup is in place
Remove the cup if it makes urination difficult or painful.
If the symptoms settle after removal and recur every time you use the same cup, consider a softer, narrower or differently shaped option.
Browse our comfort-focused period care options for sensitive bladders for products grouped around this need.
Seek medical advice if pain, difficulty urinating or other bladder or bowel symptoms continue after the cup has been removed.
What if the menstrual cup stem is rubbing or poking?
If your cup's stem sits close to or outside the vaginal opening, it may rub, pinch or poke when you sit, walk or exercise.
If the cup body itself feels comfortable and only the stem is causing irritation, check whether the manufacturer allows the stem to be trimmed.
If trimming is permitted:
- remove the cup before trimming
- use clean scissors
- remove only a small amount at a time
- do not cut into the base of the cup
- make sure you do not leave a sharp or rough edge
- wash the cup before reinserting it
If the base of the cup itself sits too low, trimming the stem will not solve the problem. In this situation, the cup body may simply be too long for your anatomy.
Why does my menstrual cup hurt when I remove it?
Pain during removal is often caused by trying to pull the cup down before releasing its seal or by pulling the rim through the vaginal opening while it is still fully expanded.
How to remove your cup more comfortably
- Wash and dry your hands.
- Choose a position in which you can comfortably reach the cup.
- Relax your pelvic floor and gently bear down, as if having a bowel movement, to help bring the cup within reach.
- Use the stem only to help locate the cup rather than pulling the cup out by the stem.
- Pinch the base or slide a finger alongside the cup and press the wall inward to release the seal.
- Keep the seal released while gently moving the cup lower.
- As the rim reaches the vaginal opening, partially fold or angle it rather than pulling the fully expanded rim straight through.
That last step is particularly important. Even if the seal has been released, a fully expanded rim can feel too wide or create a sudden stretching sensation during removal.
If the cup moves higher when you try to reach it, stop pulling or straining. Repeated attempts can make the pelvic floor tighten and make removal more difficult.

Pelvic floor and other health considerations
Sometimes the cup is not the only factor contributing to pain.
An overactive pelvic floor, vaginismus, vaginal or vulval pain, vaginal dryness and other pelvic-health conditions can make internal period products uncomfortable.
A tilted or retroverted uterus does not automatically prevent you from using a menstrual cup, but the direction of the cervix may influence cup positioning.
Pelvic organ prolapse can also change the available space and how an internal period product feels.
If you regularly experience:
- pelvic or vaginal pain
- pain during penetration
- difficulty inserting tampons, cups or fingers
- persistent bladder or bowel symptoms
- vaginal pressure or heaviness
- a vaginal bulge
- pain that occurs even when you are not using your cup
consider speaking with a GP or pelvic health physiotherapist rather than continuing to experiment with progressively smaller, softer or differently shaped products.
You can use our directory to find a pelvic health physiotherapist in Australia.
What if your menstrual cup hurts and you have an IUD?
If you use a menstrual cup with an intrauterine device, take particular care during removal.
Release the cup's seal fully before bringing it down and avoid pulling forcefully on the stem. Take care not to catch the IUD threads between the cup and vaginal wall.
New or unusual pelvic pain when you have an IUD deserves medical review rather than assuming the menstrual cup is responsible.
Seek advice from your healthcare professional if:
- you develop new or unusual pelvic pain
- you cannot feel your IUD threads when you normally can
- the threads feel substantially longer or shorter than usual
- you can feel part of the IUD itself
- you think the IUD may have moved

Would a different menstrual cup be more comfortable?
Possibly. But the answer is not necessarily a generically “smaller” cup.
Depending on the problem, you may need a cup that is:
- shorter if the cup body feels too long or presses against a low cervix
- longer or easier to reach if removal is difficult with a high cervix
- narrower if insertion, removal or internal width feels uncomfortable
- softer if bladder or pelvic pressure is the main issue
- firmer if your current cup repeatedly remains collapsed and extensive manipulation is causing discomfort
- a different shape if the cup's width sits in an uncomfortable part of the vaginal canal
- easier to grip if reaching or controlling the cup during removal is difficult
For example, you can compare our narrow-shaped menstrual cups, low-cervix options and high-cervix options.
Use the Menstrual Cups Comparison Chart to compare actual length, diameter, shape, firmness, capacity and removal designs rather than relying only on small or large labels.
Would another period product suit you better?
Sometimes the issue is not finding another menstrual cup at all.
A menstrual disc sits differently from a cup. Its reservoir sits beneath the cervix with the rim supported by the vaginal fornix and pubic bone rather than opening within the vaginal canal in the same way as a cup.
Some people who find cup pressure uncomfortable prefer a disc, although discs have their own fit and removal considerations and are not automatically more comfortable for every body.

When should you stop using your menstrual cup?
Stop using the cup and seek medical advice if you experience:
- sharp, severe, worsening or persistent pain
- pain that continues after the cup has been removed
- difficulty or inability to urinate
- unusual vaginal discharge or odour
- bleeding that is different from your usual period
- new or unexplained pelvic or abdominal pain
- repeated pain with any form of vaginal penetration
If you cannot remove a cup, it is causing severe pain or you cannot urinate, seek medical help rather than continuing to pull or force it.
Toxic shock syndrome
Toxic shock syndrome is rare but can be life-threatening.
Remove your cup if you can do so safely and seek urgent medical care if you develop symptoms such as:
- a sudden high temperature
- vomiting or diarrhoea
- dizziness or fainting
- confusion
- muscle aches
- a widespread red rash that may resemble sunburn
Always follow the cleaning, care and maximum wear-time instructions supplied with your particular menstrual cup.
Frequently asked questions
Is it normal for a menstrual cup to hurt the first time?
A cup can feel unfamiliar during your first few attempts, but sharp or significant pain should not be considered a normal part of learning.
Stop, remove the cup and work out whether the discomfort is coming from insertion, fit, pressure or removal rather than repeatedly
