The menstrual disc is very different from the cup and offers many unique advantages you won’t find with any other period protection:
- Have sex during your period 💋
- Self-emptying system 🔄
- High capacity 🩸, and more...
We break down the key differences between these two options in this article and help you choose the one that fits your needs best based on your situation.
What Is a Menstrual Disc?
As a reminder, a menstrual disc is an internal protection that sits just below the cervix (in the fornix).
Like a menstrual cup, it’s made from medical-grade silicone and acts as a reservoir to collect your menstrual blood, offering a more eco-friendly alternative to traditional tampons and pads.
Differences Between a Menstrual Cup and a Menstrual Disc
The Shape: Menstrual Disc vs. Menstrual Cup
As you can see, the menstrual disc differs mainly by its shape. A disc is much flatter and wider than a menstrual cup. The disc is also very similar to a diaphragm (a contraceptive device).
At first glance, the size of a disc might seem intimidating because it looks much bigger.
But thanks to its flexibility, it’s actually very easy to fold and insert, often even easier than a cup.
Positioning: Menstrual Disc vs. Menstrual Cup
As shown above, the menstrual disc sits higher in the vaginal canal, just below the fornix. Its shape allows it to adapt naturally to your body without needing suction to stay in place. The back of the disc tucks behind the cervix, while the front rests just behind the pubic bone.
In contrast, a menstrual cup stays lower in the vaginal canal and is held in place by creating a suction seal (similar to a gentle vacuum effect).
These fundamental differences between a menstrual cup and a menstrual disc affect not only how they are inserted and worn but also your overall experience during your period, with each offering unique advantages and disadvantages.
Is a Menstrual Disc Better Than a Menstrual Cup?
The Benefits of a Reusable Menstrual Disc Compared to a Menstrual Cup
-
IUD Compatibility :With a menstrual disc, there’s a lower risk of dislodging your IUD compared to a menstrual cup. Since the disc stays in place without suction and its shape naturally reduces expulsion risks, it's a safer option if you have an IUD. Learn more about menstrual discs and IUDs here.
-
Designed for Heavy Flows : According to an American study, menstrual discs can hold the most flow of any internal protection, up to 80 ml, which is 2 to 3 times more than a standard menstrual cup.
-
More Comfortable Than a Menstrual Cup : Menstrual discs are often praised for their softness and flexibility. The absence of a stem, while intimidating for some, usually makes discs more comfortable and less irritating. Plus, the fornix (where the disc sits) is less sensitive than the vaginal canal.
-
Sex During Your Period : With a menstrual disc, you can have penetrative sex while wearing it. Unlike a cup, the disc doesn’t block the vaginal canal and sits higher up, causing no discomfort during intimacy. Learn more about sex during your period here.
-
Easier Insertion : According to some users, menstrual discs are easier to insert than cups due to their greater flexibility and softness. However, this can vary from person to person.
-
Auto-dumping : Menstrual discs allow you to empty your protection without removing it by simply bearing down with your pelvic muscles. This is super convenient, especially when you don’t have access to a sink or when you’re traveling. Learn more about auto-dumping with a menstrual disc here.
- Reusable and Disposable Options : Menstrual discs are available in both reusable and disposable versions. Reusable discs are great for daily use, while disposable ones are ideal for those who don’t have time to clean their protection or who are traveling. Discover our Disposable Silicone Menstrual Disc.
The Downsides of a Menstrual Disc Compared to a Menstrual Cup
-
Sizing Can Be Tricky : Finding your correct disc size can be difficult because it depends on your fornix, which is hard to measure. That's why at Cup&Co, we offer a Buy 1, Get 1 Free deal, so you can try both sizes and choose the one that fits best. Click here to access our special offer on reusable menstrual discs.
-
Messier Removal : Removing a menstrual disc without spilling can be trickier than removing a cup. We recommend changing your disc in the shower or in a restroom with a sink nearby for easier hand washing afterward. Using the auto-dumping method before removing the disc can also make the process cleaner.
-
Can Be Harder to Master : Getting the hang of using a disc may take more practice than using a cup, but it really depends on each person. Some find it easier, others may need a few cycles to feel completely comfortable.

Which One to Choose: Menstrual Disc or Menstrual Cup?
Menstrual Disc or Cup for Beginners
If you’ve never tried either protection before, it’s normal to need a little time to adjust.
With both options, some women get it right on the first try, while others take a bit longer to feel comfortable. That’s why we recommend choosing the protection that makes you feel most confident and at ease.
At Cup&Co, we’re big fans of the menstrual disc because it can make your period more comfortable and easier to manage every day.
We even offer a special Beginner’s Pack where you get 1 menstrual disc + 1 free, along with a 90-day guarantee so you can really take the time to try it out.
We also offer a 90-day guarantee on our menstrual cup, making it another great option for beginners!
Menstrual Disc or Cup for Active Women and Travelers?
If you’re active or often on the go, the menstrual disc might be a better fit for you.
Unlike a menstrual cup, a disc can self-empty, which makes it much easier to manage in public restrooms. Plus, you can also choose the disposable version, allowing you to simply toss it in the trash without needing to rinse or wash it, perfect for travel or busy days!
Menstrual Disc or Cup for Moms?
Many of our menstrual disc customers are moms!
Most of them used to rely on a menstrual cup but switched to a disc after giving birth because they experienced more frequent leaks with their cup. This is completely normal, after childbirth, the vaginal canal can become wider, making it harder for tampons and menstrual cups to stay securely in place.
A menstrual disc, however, sits higher in the fornix and stays in place naturally, even after giving birth.
Menstrual Disc or Cup if You Have an IUD?
In this case, we strongly recommend choosing the menstrual disc, as it is perfectly compatible with an IUD. On the other hand, using a menstrual cup could increase the risk of IUD expulsion, according to an American study published in 2020.

If you’re unsure, you can always ask your gynecologist for advice to help you make the best choice.
