How to Choose a Pee-Safe Menstrual Cup Size: Step-by-Step Guide

Menstrual cups are an eco-friendly and cost-effective way to manage your period. But for many, especially beginners, one key concern is: How do I choose a menstrual cup that’s pee-safe — meaning it won’t irritate or press uncomfortably around my urethra?

Choosing the right size and shape for your body is essential for comfort, leak protection, and bladder health. This blog will guide you through the steps to select a pee-safe menstrual cup that fits you perfectly.

Why Is “Pee-Safe” Important?

The urethra is the small opening just above the vaginal opening, and some menstrual cups, if too large or improperly positioned, can press against it, causing discomfort or a frequent urge to urinate.

A pee-safe menstrual cup fits comfortably inside the vagina without pressing on the urethra, letting you go about your day worry-free.

Step 1: Know Your Anatomy

  • Cervix Height: Measure your cervix height by inserting a clean finger into your vagina until you feel the cervix. If it’s low, choose a shorter cup to avoid pressure.

  • Urethra Position: The urethra is typically located near the front wall of the vagina, so cups that are wide or have a firm rim may cause pressure if not sized properly.

Step 2: Choose the Right Cup Size

  • Small Size: Best for beginners, younger users, or those with a low cervix and sensitive bladder. Small cups are usually softer and shorter, minimizing urethral pressure.

  • Medium Size: For most people who haven’t given birth vaginally or are over 30 with medium flow.

  • Large Size: For heavy flow or vaginal births but may risk urethral pressure if you have a sensitive bladder.

Step 3: Consider Cup Firmness

  • Soft Cups: More flexible and less likely to press against the urethra, but can be harder to open fully.

  • Firm Cups: Easier to pop open but may press more firmly on sensitive areas.

If you’re prone to bladder sensitivity, opt for a softer cup.

Step 4: Choose a Cup with a Comfortable Rim Shape

Look for menstrual cups with rounded or tapered rims rather than thick, rigid edges. This helps reduce pressure on the urethra and surrounding tissues.

Step 5: Check Cup Length and Stem

  • Shorter cups and trimmed stems reduce the chance of irritating the urethra or bladder neck.

  • You can always trim the stem if it feels too long.

Step 6: Test and Adjust

After insertion, if you feel pressure near your urethra or discomfort when urinating, try:

  • Adjusting the cup position by rotating or pushing it slightly.

  • Switching to a smaller or softer cup model.

  • Trimming the stem for added comfort.
