"One in four people who menstruate experience heavy periods that interfere with their life." – Jean Hailes for Women’s Health

If you’ve ever soaked through a pad or tampon in under two hours, doubled up on protection, or avoided leaving the house altogether, you’re not alone. Heavy menstrual bleeding, also known as menorrhagia, can be physically and emotionally exhausting. But there are ways to manage it – and in many cases, improve it.

what qualifies as heavy bleeding?

It’s more than just a “heavy day.” Clinically, heavy menstrual bleeding is defined as losing 80ml or more of blood per period, or bleeding that lasts longer than 7 days. But here’s the thing – most people don’t measure. So signs to look out for include:

• Needing to change your pad or tampon every 1–2 hours
• Using multiple products at once
• Waking during the night to change protection
• Passing clots larger than a 20-cent coin
• Feeling constantly tired or low in iron

common causes of heavy periods

There are many potential reasons, and not all are serious – but they’re worth investigating:

• Hormonal imbalances (like oestrogen dominance)
• Polycystic ovarian syndrome (PCOS)
• Fibroids or polyps in the uterus
• Endometriosis or adenomyosis
• Certain medications or devices (like copper IUDs)

If your period is interfering with daily life, a trip to your GP is a good next step. They may suggest blood tests, imaging, or refer you to a specialist.

everyday management tips for heavy flow

track your symptoms

Use a period app or journal to monitor flow, duration and related symptoms. This helps you spot patterns and advocate for yourself in medical appointments.

support your body with the right nutrition

Focus on iron-rich foods (like red meat, legumes and leafy greens), vitamin C for absorption, and magnesium to support cramps. If you’re feeling depleted, ask your doctor about a blood test.

choose high-capacity protection

The best period product for heavy flow is one that keeps up with you – not the other way around. That’s why the my mimi menstrual disc has been a lifeline for many.

why the my mimi disc works for heavy periods

Winner of the “Best Sustainable Period Care Solution in Australia for 2025” award, the my mimi disc is designed for real life. It comes in two sizes:

• Small: 32ml capacity – holds up to 5 regular tampons
• Large: 61ml capacity – holds up to 7 regular tampons and is recommended for those over 30 or who have given birth vaginally

Unlike menstrual cups, it sits comfortably at the base of the cervix, and because it collects (not absorbs), it’s gentle on your body. The unique loop tab for easy removal makes it especially beginner-friendly, even on your heaviest day.

real stories:

"My periods have always been super heavy. Like, bleeding through my jeans heavy. I used to change my tampon and pad every hour and still worry. It was draining. I saw my mimi mentioned in a group online and gave the large disc a try. Best decision I’ve made. The capacity is incredible, and I only need to change it twice a day now. The loop tab made removal way easier than I expected. I’ve even worn it overnight without leaks. For the first time, I can actually sleep during my period. Honestly, I tell everyone - my mimi has changed how I feel about my cycle." - Lauren from Camberwell, Australia.

when to seek professional help

Heavy bleeding isn’t something you have to live with in silence. If your period is making you anxious, tired or constantly uncomfortable, speak with a GP. Treatment could include medication, hormone therapy or further investigation. You deserve answers and support.
