What Is a Menstrual Disc?

A menstrual disc is a reusable alternative to tampons and pads that collects menstrual fluid rather than absorbing it. Like a cup, a disc is worn inside the vagina, but it sits in a different place. Instead of sitting low in the vaginal canal, a menstrual disc tucks into the vaginal fornix, which is the space just below and behind your cervix. The rim rests in the area behind the pubic bone, and the basin collects your flow.

During your period, the uterine lining sheds and exits through the cervical opening. With a tampon, this fluid is absorbed. With a pad, it exits the vagina and is absorbed externally. With a menstrual disc, the blood collects in the basin until you remove and empty it.

Most menstrual discs can be worn for up to 12 hours. Your exact wear time depends on your flow. People with an average flow can often go the full 12 hours, while people with a heavier flow may need to empty more often. Some disc users also experience “auto-dumping,” which is when the disc empties small amounts on its own while you use the bathroom, extending wear time for many users.

How to Insert a Menstrual Disc

Insertion is usually quick once you learn the technique.

1. Fold or pinch the rim

Most discs insert with a simple pinch fold:
Pinch the disc’s rim together lengthwise. All discs fold in half to insert - easy peasy!

2. Insert the disc

Guide the disc into the vagina at a slight downward angle (aiming toward the tailbone). Push it back and down until the basin settles into the fornix, below the cervix.

3. Tuck the rim behind the pubic bone

This part matters most for a leak-free fit. Once the back of the disc is in place behind the cervix, use a finger to lift the front rim up and tuck it securely behind your pubic bone. This creates stability and helps the disc stay in position.

Learning the angle and the depth may take a little practice. You can absolutely practice when you are not on your period.

How to Know if Your Disc Fits Well

A menstrual disc fits correctly if:

• You cannot feel it during wear

• It stays tucked behind the pubic bone

• It does not leak (once you learn proper placement)

Most users get consistent, comfortable results after one to three cycles of practice. Many people wear a liner or period underwear during the learning phase.

If you have a very low cervix or certain anatomy needs, you may need a specific disc shape, firmness, or size. That is exactly where the Period Nirvana Quiz shines.

How to Remove a Menstrual Disc

Removal can feel intimidating at first, but it becomes very easy once you learn your technique.

1. Relax your muscles

Tension lifts the disc higher, so take a breath and let your pelvic floor drop.

2. Hook a finger under the front rim

Reach in and slide your finger upward until you feel the front rim. Hook your finger under the rim and pull it forward and down.

3. Keep it level

Once the rim is out, keep the disc as level as possible to avoid spills. If you are removing it in the shower, simply tip and empty toward the drain. Over the toilet, dump the contents carefully.

4. Rinse and reinsert

Wash the disc with warm water and a disc-safe cleanser if needed, then reinsert.

If you have long nails or trouble reaching the rim, discs with removal loops or stems can help make the process easier.

Tips for Menstrual Disc Success

1. Angle matters
Aim toward your tailbone during insertion and make sure the back of the disc is fully behind the cervix.

2. Make sure the front rim is tucked
A secure tuck behind the pubic bone is the number-one factor for preventing leaks.

3. Try different removal positions
Squatting, sitting on the toilet, or standing with one leg up can help you reach the rim more easily.

4. Learn your cervix height
A high or low cervix may influence which disc shape or firmness works best for you. Most people will fit a one-size disc, but if your disc slips during wear you may need to size up or down.
