FAQs about how to use a menstrual cup

If you still have questions about how to use a menstrual cup, we're going to answer them here.

Are menstrual cups good for beginners?
Every person who menstruates can start using a menstrual cup at any age, any time. This includes whether your hymen is intact or not. Read our take on the best menstrual cups for beginners if you need help to choose the right cup for you.

Is a menstrual cup safe?
Recent studies prove that menstrual cups are safe. They're also safer than using tampons when it comes to Toxic Shock Syndrome. Because a menstrual cup doesn't absorb menstrual blood, the risk of TSS is very low. All menstrual cups are body-friendly, and Ruby Cup's medical-grade silicone is vegan and free from plastic and bleach.

Can you sleep with a menstrual cup?
You can sleep with a menstrual cup leak-free and no longer worry about staining your bedsheets. We recommend emptying your menstrual cup every 8 hours during the day and as soon as you get up in the morning.

Does using a menstrual cup hurt?
When inserted and placed correctly, your menstrual cup shouldn't hurt. Most people forget they're wearing a cup because it's so comfortable. If you experience any pain, check if your cup is open and positioned correctly, or try a softer cup. Always check with your gynecologist first to rule out any health issues before changing cups.

How far up should a menstrual cup go?
A menstrual cup should sit lower than a tampon in your vaginal canal, below your cervix. Also, inserting a tampon vs a menstrual cup is different. Instead of inserting a cup vertically and up like a tampon, insert your menstrual cup horizontally and back toward your tailbone.

Does a menstrual cup get stuck?
A menstrual cup can't get stuck and you can't lose your cup inside your vagina. If you have trouble removing your menstrual cup, always remember to release your cup's suction by pinching its base or pressing a finger between your cup and vaginal wall.


How do you clean a menstrual cup?

During your period, rinse your menstrual cup under clean running water every time you empty your cup. Between periods, sterilize your cup in boiling water for 5 minutes. When using a public bathroom, use a water bottle to clean your cup over the toilet, or wipe your cup with tissues or toilet paper, then reinsert.


Do menstrual cups leak?
Menstrual cups won't leak when inserted correctly. A leaking cup is a cup that hasn't opened and formed a seal. To prevent leaking, run your index finger around the base of the cup. If you feel any creases, your cup hasn't opened. Just gently grip the base and rotate your cup until you feel it open.


How do you know when to change your menstrual cup?
Our medical-grade silicone Ruby Cups can last up to 10 years. Heavy stains, cracking, and changes in texture are signs to replace your cup. Emptying your menstrual cup every 8 hours, rinsing after each use, and sterilizing between periods will help your menstrual cup last for as long as possible.


What's the best eco-friendly period product?
Menstrual cups are the best eco-friendly period product because they are reusable for up to 10 years. Even when you compare menstrual cups vs reusable pads, cups are easier to care for and clean, using less water than any other reusable period product. A menstrual cup is the most responsible zero-waste choice.
