What Is a Menstrual Disc? A Full Guide

The menstrual disc is changing period care for good. Unlike pads or tampons, a disc collects fluid for up to 12 hours, giving you comfort, freedom and fewer changes. It sits higher than a cup, feels barely there, and suits busy days, travel and sleep. This guide explains how discs work, why so many Australians prefer them, and why the my mimi menstrual disc is a favourite for beginners, IUD users and anyone wanting comfortable period sex.
What Is a Menstrual Disc?
A menstrual disc is a soft silicone device that sits in the vaginal fornix just below the cervix. It tucks behind the pubic bone and is held in place by your anatomy, without suction. To use it, fold, insert, let it settle, then remove via the loop tab to empty, rinse and reinsert. Many users can also semi-empty during a toilet visit on heavy days for longer wear.

Why People Love Menstrual Discs
- Comfort you can’t feel: Sits higher than a cup and moulds to your shape.
- All-day wear: Up to 12 hours, including overnight and exercise.
- Higher capacity: Great for heavier flow and longer stretches.
- IUD friendly: No suction means low risk of disturbing strings.
- Period sex: Worn during penetrative sex for mess-reduction and confidence.
- Reusable: Lasts 5+ years and costs about 83c per month over its life.
Menstrual Disc vs Menstrual Cup
| Feature | Menstrual Disc | Menstrual Cup |
|---|---|---|
| Position | Upper vaginal fornix | Vaginal canal |
| How it stays in | Tucked behind pubic bone, no suction | Suction seal |
| Comfort | Soft, flexible, often undetectable | Can cause suction pressure |
| Capacity | Higher, suits heavy flow | Moderate |
| Period sex | Yes | No |
| IUD suitability | Ideal, suction-free | Use caution |
Which Size Should I Choose?
my mimi offers two sizes to suit different bodies:
- Small (32 mL): Often suited to teenage users and people under 30 or who haven’t given birth vaginally.
- Large (61 mL): Often suited to users over 30 or who have given birth vaginally.
