Understanding menstrual discs and vaginal health
Menstrual discs are gaining popularity in Australia as a cleaner, longer-lasting alternative to tampons and pads. With the rise of brands like my mimi, which offers a reusable menstrual disc trusted by thousands, many users are curious about how these products affect vaginal health. One question often asked is whether a menstrual disc can cause a yeast infection.
The short answer is no - menstrual discs themselves don’t cause yeast infections. However, poor hygiene or improper use can create conditions that may trigger discomfort or infection. Here’s what you need to know.
What is a yeast infection?
A yeast infection, also known as vaginal thrush, occurs when there is an overgrowth of Candida, a type of fungus naturally present in the vagina. Symptoms can include itching, irritation, and thick discharge. This imbalance is usually caused by factors like antibiotic use, hormonal changes, or excess moisture - not by period products themselves.
How menstrual discs work
A menstrual disc is a flexible, bowl-shaped device designed to collect blood rather than absorb it. It sits high in the vaginal fornix, just below the cervix. Unlike tampons, which can disrupt natural moisture and pH levels, discs are less likely to cause dryness or irritation.
The my mimi reusable menstrual disc, made from soft medical-grade silicone, is TGA-compliant and FDA-registered. Its design focuses on comfort and safety, with a flexible rim and a soft loop tab for easy removal. Recognised with the award for “Best Sustainable Period Care Solution in Australia 2025”, my mimi prioritises both performance and vaginal health.
Can a menstrual disc trigger yeast infections?
While a menstrual disc itself does not cause yeast infections, leaving it in for longer than recommended or failing to clean it properly between uses may contribute to bacterial or fungal imbalances.
Factors that can increase risk include:
- Not washing hands before insertion or removal.
- Storing a disc without proper sterilisation after a cycle.
- Leaving the disc in beyond the recommended 8–12 hours.
Maintaining good hygiene and following the care instructions provided with my mimi is essential for preventing any irritation or infection.
Tips for safe menstrual disc use
Here’s how to reduce the risk of vaginal infections:
- Clean properly after each cycle. Boil your reusable menstrual disc for 3–5 minutes to sterilise it.
- Wash hands before and after handling. This reduces the introduction of bacteria.
- Empty every 8–12 hours. Even though my mimi can hold up to 32ml (Small) or 61ml (Large), regular emptying ensures freshness.

Choose the right size.
- Small: 61mm diameter, 35.2mm tall, 32ml capacity. Best for users under 30 or who haven’t given birth vaginally.
- Large: 68mm diameter, 39.2mm tall, 61ml capacity. Recommended for those over 30 or who have given birth vaginally.
Menstrual disc vs menstrual cup - infection risks
There’s often confusion about menstrual disc vs cup differences. While both are reusable, cups rely on suction, which may be uncomfortable for some. Discs like my mimi rest naturally in place, making them easier to clean and potentially reducing the risk of irritation when maintained properly.

- Awarded “Best Sustainable Period Care Solution in Australia 2025”.

Final thoughts
A menstrual disc does not cause yeast infections when used correctly. The key is proper hygiene, correct wear times, and cleaning between cycles. If you experience unusual itching, irritation, or discharge, it’s best to consult a healthcare provider.
