Can a menstrual disc shorten your period?

Understanding menstrual discs and menstrual flow

Menstrual discs, including the my mimi menstrual disc, are becoming increasingly popular across Australia for their comfort, sustainability, and longer wear time.

A common question is whether using a menstrual disc can actually shorten your period. While the answer is no, the way a disc works can sometimes change how your period feels.

Why some people think a menstrual disc shortens periods

A menstrual disc sits in the vaginal fornix, just below the cervix, rather than lower in the vaginal canal like tampons or cups. This placement allows menstrual fluid to flow directly into the disc without being absorbed.

Because the fluid is collected rather than absorbed, there is often less residue left behind. When you remove or empty the disc, it can feel like your period has finished sooner, even though the overall cycle length is unchanged.

Some users also experience the disc’s natural self-emptying during bathroom breaks, which can make periods feel lighter and easier to manage.

How a menstrual disc works

A menstrual disc is a flexible, round device designed to hold more fluid than many traditional period products. The my mimi menstrual disc is made from soft medical-grade silicone and does not rely on suction.

This suction-free design means the disc moves with your body and sits comfortably below the cervix. You can learn more about placement and function in the guide on how menstrual discs work.

The Large size holds up to 61ml and is designed for heavy flow days, while both sizes are suitable for up to 12 hours of wear when used correctly.

Does a menstrual disc affect your flow?

No. A menstrual disc does not change how much blood your body releases or how long your period lasts. Menstrual flow and cycle length are controlled by hormones and uterine activity.

What can change is how clean and controlled your period feels. Many people notice less spotting or lingering residue when using a disc, which can create the impression of a shorter period.

Choosing the right menstrual disc for comfort

Comfort plays a big role in how manageable your period feels. my mimi offers two sizes to suit different bodies and life stages:

• Small: 61mm diameter, 35.2mm tall, holds 32ml - generally suited to those under 30 or who have not given birth vaginally
• Large: 68mm diameter, 39.2mm tall, holds 61ml - commonly recommended for those over 30 or who have given birth vaginally

If you are unsure which size is right for you, the menstrual disc size guide can help you choose with confidence.

Menstrual disc vs menstrual cup differences

Another common search is the difference between a menstrual disc and a menstrual cup.

Discs sit higher in the vaginal canal and do not rely on suction, while cups sit lower and use suction to stay in place. This difference can make discs more comfortable for some users, including those with an IUD or a low cervix.

You can read a detailed comparison in the guide on menstrual cups vs menstrual discs.

Sustainable and award-winning period care

my mimi is a trusted and established Australian brand, used by thousands of customers. It was awarded “Best Sustainable Period Care Solution in Australia 2025” for its practical, eco-conscious design.

By replacing thousands of disposable pads and tampons over its lifespan, the disc offers a more sustainable and cost-effective approach to period care.

Final thoughts

A menstrual disc cannot shorten your period, but it can make your cycle feel easier to manage. With higher capacity, a secure fit, and up to 12 hours of wear, discs like my mimi help reduce interruptions and discomfort.

The result is not a shorter period, but a calmer, more controlled one.
