Menstrual cup FAQs
How long can you leave a menstrual cup in?
Most brands suggest that you can leave your cup in for up to 12 hours. You should check the packaging/website for the recommended maximum time you can leave yours in for. If you have a particularly heavy flow, you might feel like you want to change yours more regularly than usual, if only for peace of mind.
Can you wear menstrual cups overnight?
As long as you do not leave it in for longer than the time detailed on the packaging, you can sleep with it in. Because cups tend to be very comfortable, you may find that you prefer sleeping with it in than with, say, a sanitary pad.
Where do you buy menstrual cups?
You can buy them from most pharmacies, many supermarkets and lots of online retailers.
Can you pee with a menstrual cup in?
You can pee and poo with one in. Unlike tampons, cups don't have a long string, so there's no chance of unwanted, lingering bacteria.
Can you have intercourse with a menstrual cup in?
You cannot have sex when using a reusable menstrual cup. They're too rigid and it wouldn't be safe. However, you can buy disposable ones that can be worn during sex. You should check the packaging to make sure yours is marked as being safe for use during sex.
Can you go swimming with a menstrual cup in?
Yes, you can. In fact, many women find that a menstrual cup gives them better protection from leaks than tampons.
Are menstrual cups better than tampons?
There are many reasons to love menstrual cups, and we think they're worth giving a go. Ultimately, though, it comes down to personal preference. Some people prefer pads to tampons, some prefer tampons to pads. In the same way, some people will prefer cups, some won't.
Can you wear a menstrual cup when you're not on your period?
If you're expecting your period to start, you can wear your cup in anticipation of it. Likewise, you can keep using it until your period is completely over, unlike with tampons where you often have to rely on pads for the last day or so.
Can you use a menstrual cup if you use an intrauterine device (IUD, or coil)?
The short answer is yes, you can. However, if you wish to use both together, bear the following in mind:
There should always be a space between the cup and the cervix. If you have a low-sitting cervix there may not be enough room for your cup to sit safely and work properly alongside your IUD
Place the cup low down in the vagina and ensure you have an adequate seal
Always release the seal before removing your cup
After each period, check you can still feel the IUD strings. If you cannot feel them or think that your IUD has moved or is causing you pain, use another form of contraception such as a condom until you see the doctor, who will be able to check your IUD is still properly in place
Are menstrual cups safe?
When used correctly, they are completely safe.
One of the worries with incorrect use is that you might forget to take it out at all, given that you can keep it in for up to 12 hours. If you feel like you need to, it can be an idea to set a reminder on your phone reminding you to change it.
I love, love, love my squishy friend. I’ve had it for several years now and will never go back to any other sort of sanitary product. I work, travel, do sports and just generally do everything in my life as normal with it.
Troubleshooting – menstrual cup problems solved
Help! I can't get my menstrual cup in
Just like with tampons, it can take a little while to get used to inserting your cup. If you try and don't succeed, don't stress. Carry on using your usual pads or tampons and give it a go another go the next day or next period.
I can't get my menstrual cup out
If you can't reach your cup to get it out, it's probably sitting a bit too high. Take a deep breath and do a series of small, downward pushes with your vaginal muscles. This should encourage the cup to move down far enough for you to reach the stem, break the seal and remove the cup. With a bit of practice, easy removal is in the bag.
I don't want to rinse out my cup in a public toilet – what can I do?
While we're all for waving the period flag, it's also OK not to want to wash out your menstrual cup in the sinks of a public loo. If you know you'll need to change yours while you're out and about, bring a bottle of water with you to rinse out your cup over the toilet. Alternatively, try to time your change so that you don't need to change yours when you're out.
I can still feel the stem when I have inserted my menstrual cup – what should I do?
You may find that no matter how many times you insert your cup, you still find that you can feel the stem digging in. It may be the case that you have a low-sitting cervix. Just remove the cup, trim the stem a little bit and reinsert. If you need to trim off a little more, make sure you remove the cup before doing so.
How do I fold my menstrual cup?
There are a number of different folds you could try. Just like menstrual cups, different folds suit different women, so if one doesn’t work for you, there are others to try your hand at.
The ‘C’ or ‘U’ fold - so-called because of the shape the cup makes - is the most well-known fold. Just hold the cup with both hands placed just underneath the rim, push the sides together to flatten the cup, fold the cup in half length-ways and pop it in.
Another popular fold, which is quick, straightforward and great if you are in a rush, is the punchdown fold.
All you have to do with this one is hold the cup at the base with one hand while placing the index finger of the other hand on the top of the cup rim. This finger then pushes the rim down inside the base then push the sides together and hold firmly.
But don’t worry if you are struggling as there are a number of different YouTube videos which can help you to find a technique that works for you.
Can I use a menstrual cup if I have heavy periods?
Yes, you can use a menstrual cup if you have heavy periods. You will just need to invest in a cup that has a larger capacity and expect to empty it more often.
Can I use a menstrual cup after giving birth?
The NHS says that you should not use a menstrual cup after giving birth until you have had your six-week check.
This is because you will still have a wound where the placenta was joined to the wall of your womb, plus there are likely to be cuts and tears in and around your vagina. Any sort of internal sanitary products are not recommended during this time as it increases the likelihood of infection.
Once you have healed, then you can use a menstrual cup, but you will likely need to use a different size than you were using before if you have just given birth vaginally.
How do I clean my menstrual cup?
Cleaning a menstrual cup is pretty straightforward. Just pop your cup in boiling water for five to 10 minutes before emptying the water. Once the cup has cooled, with clean hands, wash the cup with a mild, water-based, oil-free soap. Then give it a good rinse and you’re ready to go again.
Make sure you don’t use anything like vinegar, perfumed soaps, antibac, bleach or baking soda to clean your menstrual cup. Not only will this damage your cup, but you could seriously harm your vaginal health. Healthline has more great tips on how to care for your menstrual cup.
How often should a menstrual cup be replaced?
If treated with care, menstrual cups can last for several years, but it’s generally recommended that you replace your cup every two years. If your cup is damaged, has a tear or a hole in it, you’ll want to replace it sooner.
