Understanding menstrual disc hygiene and safety

Reusable menstrual discs are becoming a trusted alternative to tampons and pads in Australia. Known for their longer wear time, eco-friendly design, and comfort, they’re increasingly seen as a smarter choice for modern period care. But a question often asked is whether a menstrual disc can cause an infection.

The short answer is no - when used correctly and kept clean, a menstrual disc should not cause infection. Like any internal period product, hygiene is key to maintaining a healthy balance of bacteria in the vagina. Let’s break down the facts.

What is a menstrual disc?

A menstrual disc is a flexible device that sits in the vaginal fornix, just below the cervix, collecting menstrual blood rather than absorbing it. Unlike tampons, discs do not disrupt the natural vaginal environment or cause micro-abrasions that may increase infection risk.

The my mimi reusable menstrual disc, made from medical-grade silicone, is TGA-compliant and FDA-registered for safety. Designed with a soft loop tab for easy removal, it has been awarded “Best Sustainable Period Care Solution in Australia 2025” for its focus on comfort, sustainability, and affordability.

Can menstrual discs cause infections?

Menstrual discs themselves do not cause infections. However, improper use - such as leaving the disc in for longer than recommended or not cleaning it thoroughly - can create conditions where harmful bacteria grow.

Unlike tampons, which can absorb moisture and disturb the vaginal pH, discs simply collect blood. This reduces the risk of irritation and dryness. That said, any foreign object left inside the body for too long can pose a risk. Following correct usage and cleaning instructions is essential for avoiding infection.

How to reduce infection risk with a menstrual disc

To stay safe, these hygiene practices are recommended:

• Clean thoroughly between uses - After removal, wash your reusable menstrual disc with warm water and a mild, fragrance-free cleanser. Boil the disc for 3-5 minutes at the end of your cycle.
• Empty every 8–12 hours - The my mimi disc can hold up to 32ml (Small) or 61ml (Large), offering all-day or overnight wear. However, emptying and rinsing the disc twice daily ensures hygiene and freshness.
• Wash your hands before insertion and removal - This simple step reduces the chance of introducing unwanted bacteria.
• Choose the right size - my mimi comes in two sizes:
  • Small: 61mm diameter, 35.2mm tall, 32ml capacity (recommended for users under 30 or those who have not given birth vaginally).
  • Large: 68mm diameter, 39.2mm tall, 61ml capacity (recommended for users over 30 or those who have given birth vaginally).

Signs of infection to watch for

If you notice unusual odour, itching, discomfort, or unusual discharge while using any internal period product, remove it immediately and consult a healthcare professional. These symptoms are not caused by the disc itself but could indicate bacterial imbalance or other vaginal health issues.

Menstrual disc vs menstrual cup: infection risk

When comparing menstrual disc vs cup, the risk of infection is similar - both are safe when cleaned properly. Some people prefer discs because they don’t rely on suction, making them easier to insert and remove. my mimi’s soft loop tab makes removal even simpler, reducing the chance of unnecessary handling or accidental mess.
