Is your period disc to blame for back discomfort?
Menstrual discs are becoming a favourite alternative to tampons and pads. They’re sustainable, comfortable, and can be worn for longer periods of time. But some people wonder if using a disc could be linked to back pain.
The short answer is no - a menstrual disc doesn’t cause back pain directly. Period-related back pain is usually due to natural uterine contractions, not the product you’re using. Still, incorrect placement or size can sometimes add to existing discomfort.
Why do periods cause back pain?
Back pain during menstruation is caused by prostaglandins - hormones that trigger the uterus to contract. These contractions can radiate pain into the lower back, pelvis, or thighs. This can happen whether you use a tampon, pad, menstrual cup, or disc.
Could your menstrual disc add to the pain?
A menstrual disc is designed to sit high in the vaginal fornix, resting just behind the pubic bone. It doesn’t rely on suction or cause pulling on vaginal walls, so it’s unlikely to cause pain when inserted correctly.
However, some discomfort can occur if:
- The disc is inserted at the wrong angle.
- The size doesn’t suit your anatomy.
- Pelvic floor muscles are tense or contracting.
How to make menstrual discs more comfortable
- Angle it properly: Insert the disc towards the tailbone and ensure it sits fully behind the pubic bone. If it’s positioned correctly, you shouldn’t feel it.

Choose the right size: my mimi comes in two sizes:
- Small: 61mm diameter, 35.2mm tall, 32ml capacity - best for those under 30 or who haven’t given birth vaginally.
- Large: 68mm diameter, 39.2mm tall, 61ml capacity - recommended for those over 30 or who’ve had a vaginal birth.
- Relax and re-check placement: If you feel pressure or discomfort, remove and reinsert. A warm shower can help relax muscles for easier placement.

Menstrual disc vs menstrual cup
A menstrual disc vs cup comparison shows that discs are often easier for beginners. Unlike cups, which rely on suction, discs stay in place naturally and can be worn during sex. This makes them more comfortable for many users.
When to get advice
If you continue to experience back pain even when your disc is inserted correctly, the discomfort is likely unrelated to the product. Persistent pain should always be checked by a healthcare professional.
Final thoughts
A menstrual disc isn’t known to cause back pain. It’s designed to feel invisible while offering long-lasting protection. For most people, my mimi makes periods simpler, more comfortable, and better for the planet.
