What is a Menstrual Disc?

A menstrual disc is a soft, internal period product designed to collect, not absorb, menstrual fluid. Unlike a tampon which sits in the vaginal canal, a disc sits higher up at the base of the cervix. Think of it as sitting in a gentle, sloping spot where the vaginal canal widens. Once in place, the rear edge sits behind the cervix while the front edge tucks behind the pubic bone. Discs do not rely on suction to stay secure and, when positioned correctly, many users find they cannot feel them during daily activities. Read a complete beginner’s guide to menstrual discs [source needs verification] for more details on placement and comfort.

Why Haven’t You Heard About Discs?

Most period education has focused on pads and tampons, with some mention of menstrual cups. Discs are newer to the mainstream and can seem confusing at first glance. But the reason you have not heard about them is not because you missed something - it is because period care options have only recently begun to expand beyond the basics. Emerging brands like my mimi exist to fill that gap, making it easier to understand and try discs for yourself.

Why Try a Menstrual Disc?

A menstrual disc can be worn for up to 12 hours, depending on your flow. Because it is positioned high in the vaginal canal, it stays out of the way during exercise, sleep, swimming, and even during sex (depending on your comfort and anatomy - see this FAQ for more). my mimi menstrual discs are made from medical-grade silicone and designed for repeated use, with Small and Large options to suit different flows. If you are new to insertion, my mimi also offers a soft-touch applicator [source needs verification] and water-based personal lubricant for extra support.

How to Use a Menstrual Disc (Step by Step)

Learning to use a disc can take a little practice, but with a clear guide most people feel confident after a few tries.

1. Wash your hands thoroughly.

2. Find a comfortable position (standing, sitting on the toilet, or squatting can help).

3. Pinch the disc in the middle to make it narrow.

4. Insert it aiming slightly backwards and down, towards your tailbone rather than straight up.

5. Once fully inside, tuck the front rim behind the pubic bone.

See the beginner guide [source needs verification] for step-by-step instructions and illustrations.

Real Talk: The Learning Curve and Support

It is normal for first-time users to need a few cycles to find their perfect fit and routine. Most leaks or discomfort come from placing the disc too low or not tucking the rim fully. If you experience persistent trouble, try reviewing the troubleshooting advice or exploring if size or technique changes could help. my mimi offers resources to help with prolapse concerns, IUD use, and more.

Frequently asked questions

What is a menstrual disc?

A menstrual disc is a soft, reusable internal period product that sits high in the vaginal canal at the base of the cervix. It collects menstrual fluid rather than absorbing it, offering up to 12 hours of wear depending on your flow.

How is a menstrual disc different from a tampon or cup?

A disc sits higher in the body than a tampon or menstrual cup and does not rely on suction. It collects fluid in a wide basin, and many users find it comfortable for exercise, swimming and (for some) period sex.

Will I feel it once it is inserted?

When positioned correctly, most people cannot feel their menstrual disc during normal activity. A sensation of discomfort or pressure usually means the disc is not positioned fully in the fornix or the rim is not tucked.

Is it hard to use a menstrual disc?

There is a learning curve, but most beginners feel confident after several insertion cycles. Guides, applicators and lubricants can help with first-time use.

Can I use a menstrual disc if I have an IUD?

Menstrual discs do not rely on suction in the way cups do. If you have an IUD, take care to avoid pulling on the strings when removing your disc and seek medical advice with any concerns.

Can I exercise or swim while wearing a disc?

Yes. A menstrual disc can be worn while exercising and swimming, provided it is positioned correctly and within recommended wear time.

Can I wear a disc overnight?

A menstrual disc can be worn overnight provided wear time does not exceed the 12-hour recommended maximum and your flow allows.

Is a menstrual disc birth control?

No. A menstrual disc does not prevent pregnancy or protect against sexually transmitted infections. For more, see this page.
