Discover how reusable menstrual discs work, how to choose the right size, and tips for heavy flow days. Explore the benefits of switching to a disc.
Reusable menstrual discs are gaining popularity as a comfortable, eco-friendly alternative to tampons and pads. Unlike cups, discs sit at the base of your cervix and can be worn for up to 12 hours, making them a convenient choice for busy days. If you're curious about making the switch, this guide covers everything you need to know about how they work, sizing, and using them for heavy flow.
Whether you're new to reusable period care or looking to add a disc to your routine, understanding the basics can help you choose the right product. In this guide, we'll break down the mechanics, benefits, and practical tips for using a reusable menstrual disc.
How Do Reusable Menstrual Discs Work?
Reusable menstrual discs are shallow, bowl-like devices made of medical-grade silicone. Unlike tampons, which absorb blood, discs collect it. You insert the disc by pinching it and pushing it back towards your cervix, where it sits in the vaginal fornix. The disc's rim creates a seal against the vaginal walls, preventing leaks while allowing you to wear it for up to 12 hours.
One of the biggest advantages of discs is that they can be worn during sex, as they are positioned high up and don't interfere. They also don't cause dryness or disrupt your natural pH, making them a great option for those with sensitive skin. Plus, they're reusable for years, reducing waste and saving money.
- Discs collect rather than absorb, so there's no risk of Toxic Shock Syndrome (TSS).
- You can wear a disc for up to 12 hours, making it ideal for overnight or long workdays.
Choosing the Right Size and Fit
Unlike menstrual cups, which come in multiple sizes, most discs are one-size-fits-most. However, it's still important to consider your anatomy and flow. The Saalt Disc is designed to fit a wide range of bodies, with a soft, flexible rim that conforms to your shape. If you have a low cervix or a sensitive bladder, you might need to try a smaller option, but most people find a standard disc works perfectly.

When inserting a disc, you should not feel it at all once it's in place. If you do feel pressure or discomfort, you may need to adjust the position or try a different angle. It's normal to take a few tries to get comfortable with insertion, so be patient with yourself.
- The Saalt Disc has a finger notch for easy removal and a soft rim that springs open for a secure fit.
- Always wash your hands before inserting or removing your disc to prevent infection.
Using a Disc for Heavy Flow Days
Many people wonder if a disc can handle heavy flow. The answer is yes! A disc can hold more than a tampon or cup, making it an excellent choice for heavy days. The Saalt Disc holds up to 30ml, which is significantly more than a super tampon. You can wear it for up to 12 hours, even on your heaviest day, without worrying about leaks.
To empty the disc, simply remove it, dump the contents into the toilet, rinse it, and reinsert. It's that easy. For extra protection on heavy nights, you can pair your disc with leakproof underwear, such as the Leakproof French Cut High Waist, for peace of mind.

- Consider using a disc alongside leakproof underwear for overnight security.
- If you have a very heavy flow, you may need to empty your disc more frequently than 12 hours, but it's still less often than changing a tampon.
Reusable Discs vs. Menstrual Cups: What's the Difference?
While both are reusable, discs and cups have distinct differences. Cups sit lower in the vaginal canal and use suction to stay in place, whereas discs sit higher and rely on the pubic bone to anchor them. This makes discs less likely to cause cramping or bladder pressure. Additionally, discs are often easier to insert and remove because they don't require a perfect seal.
If you've tried a cup and found it uncomfortable or difficult to use, a disc might be a better fit. The Saalt Disc is a popular choice for those transitioning from cups. It's also a great option for people who experience discomfort with cups or who want the ability to have mess-free period sex.
- Discs don't rely on suction, so they're less likely to cause discomfort or dislodge during exercise.
- You can wear a disc while swimming, running, or doing yoga without any issues.
Caring for Your Reusable Disc
Proper care extends the life of your disc and keeps it hygienic. After each use, rinse it with warm water and a gentle, fragrance-free soap. Between periods, you can boil it for 5 minutes to sterilize. Store it in a breathable bag, like the Saalt Travel Kit, which is perfect for on-the-go cleaning and storage.
With proper care, a high-quality disc can last up to 10 years, making it a cost-effective and environmentally friendly choice. Plus, you'll never have to worry about running out of tampons or pads again.
- Avoid using oil-based soaps or lubricants, as they can degrade the silicone.
- Always air-dry your disc completely before storing it to prevent mold growth.
Reusable menstrual discs offer a comfortable, sustainable, and convenient period solution. Whether you're dealing with heavy flow or just want to reduce waste, a disc like the Saalt Disc can transform your period experience. Ready to make the switch?
