A Beginners Guide to using a Menstrual Disc

As someone who trains daily, competes professionally, and spends hours on a bike saddle, managing my period has always been an ongoing challenge. I’m a 33-year-old cyclist based in Victoria, and I’ve tried just about every period product out there - pads, tampons, even period-proof underwear. But none really worked for long rides, travel days, or back-to-back events. That was until I discovered my mimi, a reusable menstrual disc I spotted on Amazon and then again at Chemist Warehouse.

Here’s my experience using it - and why I’m staying with it.

Why I Made the Switch

In cycling, comfort and control are everything. You’re constantly balancing your body, tracking performance, and fine-tuning gear - so the last thing you need is an unreliable period product. I’d had too many close calls with tampons on long rides. Dryness. Leaks. That constant worry in the back of my mind. Plus, like many athletes, I care about sustainability and cutting back on unnecessary waste.

my mimi caught my eye because it was winning awards for innovation and sustainability. In fact, it recently took out the title of Best Sustainable Period Care Solution in Australia 2025. That told me this wasn’t just another product trying to jump on the eco bandwagon. It had credibility.

First Use: What I Noticed Right Away

The disc came in discreet packaging, with clear instructions. I opted for the small size since I hadn’t given birth and have a lower cervix. The first surprise? The feel. It was soft but not flimsy, and the loop tab at the end gave me more control over removal. That feature alone eased a lot of anxiety.

Inserting it was different to anything I’d used before. It sits higher than a tampon or cup, but once in place - it stayed there. I tested it on a 60km ride two days into my cycle. No leaks. No shifting. No awareness it was even there. For me, that was a first.

Training, Racing, and Recovery with the my mimi menstrual disc

I’ve now worn the my mimi disc while racing, during strength training, yoga, recovery sessions, and even on overnight bus trips. It’s held up through everything. The real test? A 90-minute hill interval session on day three of my cycle. Normally, I’d be checking my gear every 10 minutes for leaks or signs of shifting. This time, nothing. Just me, my ride, and zero distractions.

Even better, I could leave it in for up to 12 hours. On rest days, I wore it from morning till night without needing to empty it. That kind of freedom doesn’t just change your routine - it changes how you feel on your period.

And yes, I’ve worn it during sex. Comfortable. Clean. No disruption.

What I Tell Other Athletes Considering a Menstrual Disc

If you’re active - especially in endurance sports - you should know there’s a better way to manage your period. I’d recommend my mimi in a heartbeat. Start with the small size if you’re new or haven’t given birth. If you’ve had kids or have a heavier flow, the large size is excellent. It holds up to 61ml, so it works well on peak flow days.

Cleaning it is easy, and it dries fast between uses. The disc itself lasts five years, which makes it incredibly cost-effective - about 83 cents a month.

But a word of caution: there are other discs popping up online that aren’t always medically approved. my mimi is stocked by national names like Chemist Warehouse and international platforms like Amazon. That gives me confidence it meets both Australian (TGA) and international (FDA) standards. Always choose products that meet medical-grade requirements.
