Menstrual cups have become super popular—and for good reason. They're eco-friendly, comfy, and last way longer than tampons or pads. But some people worry: can a period cup cause a UTI (urinary tract infection)? The short answer: not directly. While cups don’t cause UTIs, certain habits can increase the risk. Let’s break it down and show you how to avoid any trouble.

What is a UTI, and What Does It Have to Do With Period Cups?

A UTI (urinary tract infection) happens when bacteria get into your urinary tract and cause irritation or infection. If you've ever had one, you know it's no fun. Common symptoms include:

• Burning when you pee

• Needing to pee all the time (even when you just went!)

• Cloudy, smelly, or strange-looking pee

• Pelvic discomfort

UTIs are more common for people with vaginas because of how short the urethra is—it makes it easier for bacteria to reach the bladder. 

But what does a period cup have to do with this? Well, it’s mostly about hygiene and positioning.

Can a Period Cup Cause a UTI?

No, a menstrual cup itself won’t cause a UTI. But like anything that goes near your body, hygiene matters. If bacteria make their way from your hands or skin into the urethra, there’s a higher chance of infection.

Here’s what might increase that risk:

1. Not Cleaning the Cup Properly

Your period cup needs a good clean between uses. If it's not washed well or sterilised between cycles, bacteria can stick around and potentially cause trouble.

2. Cup Positioned Incorrectly

The urethra and vagina are neighbours—very close ones. If your cup presses against your urethra, it can slow your pee flow or make it harder to empty your bladder properly. This can increase the chance of a UTI.

3. Touching the Cup with Unwashed Hands

Our hands carry loads of bacteria (even when they look clean). If you handle your cup without washing your hands, you might transfer bacteria to your urinary tract.

How to Prevent UTIs When Using a Period Cup

The good news? UTIs are preventable—even when using a period cup. Here are some simple steps to keep things fresh, safe, and comfortable.

1. Keep It Clean

• Wash your hands before inserting or removing the cup.

• Rinse your cup with warm water between uses.

• Sterilise it after each cycle—boil it for 3–4 minutes or use the Inoya Sterilising Cup for a super easy microwave option.

💡 Tip: Use a gentle, fragrance-free soap when cleaning your cup. Harsh or scented soaps can irritate your vagina and throw off your pH balance. 

2. Get the Cup Position Right

If your cup feels like it’s pushing on your bladder or making it hard to pee, adjust it lower.

💡 Tip: If peeing still feels tricky, your pelvic floor muscles might be a bit tight—relax, breathe, and gently bear down to make removal smoother.

3. Empty It Regularly

Leaving your cup in for too long can give bacteria time to grow. Make sure to:

• Empty and rinse your cup every 8–12 hours.

• If you have a heavy flow, empty it more often.

Regular emptying is key to keeping things healthy. 

FAQs

❓ Can a menstrual cup block my pee?

Yes, it can—if it's positioned too high or pressing on your urethra. If you feel pressure or notice a slow pee stream, try adjusting the cup lower.

❓ How do I clean my cup to avoid UTIs?

• Wash your hands first.

• Rinse your cup with warm water and mild soap after every use.

• Boil the cup for 3–5 minutes after your cycle to kill any lingering bacteria. 

❓ I’m prone to UTIs. Can I still use a period cup?

Yes! Just be extra cautious about hygiene and positioning. If you're unsure, chat with your doctor for personalised advice.

The Bottom Line

Your period cup isn’t the enemy—UTIs happen when bacteria enter the urinary tract. By:

• Washing your hands

• Cleaning your cup thoroughly

• Making sure it’s positioned correctly

…you can enjoy your period cup without the UTI worry.
