Did you know that swimming with a menstrual cup can give you hours of worry-free protection without needing a single change? It's true! These small, flexible wonders collect your flow instead of absorbing it, which is not only more comfortable but also helps reduce infection risks during your favorite water activities.
Swimming with a menstrual cup is absolutely possible and, in my opinion, a total game-changer. When properly inserted, a menstrual cup creates a secure seal with your vaginal walls, providing leak-free protection. Plus, it can hold significantly more fluid than tampons, meaning you won't have to stress about finding a restroom mid-way through your beach or pool day. These cups are made from 100% waterproof medical-grade silicone, making them perfect for any water adventure.
Key Takeaways
- Seal is Everything: A properly inserted menstrual cup creates a secure suction seal that is completely leak-proof, keeping menstrual fluid in and water out.
- Choose Wisely: Selecting the right cup size and firmness based on your cervix height, flow, and activity level is crucial for comfort and effectiveness.
- Practice Makes Perfect: Get comfortable with inserting and removing your cup at home before heading to the pool to build confidence and ensure a stress-free swim.
- Double Up for Confidence: Pairing your menstrual cup with period swimwear like Beautikini provides an unbeatable layer of backup protection for total peace of mind.
Using a cup for swimming might feel a little daunting at first, but the benefits make the learning curve completely worth it. This guide will walk you through everything you need to know to swim confidently, from choosing the right cup to pairing it with high-performance period swimwear like Beautikini for extra peace of mind.
Choosing the Right Menstrual Cup for Swimming
The key to finding the perfect menstrual cup for swimming lies in understanding your body. A well-fitted cup creates a secure seal that stops leaks dead in their tracks while you enjoy the water. Let's dive into how to select the ideal cup for your swimming needs.

How Cup Size and Firmness Affect Your Swim
Finding the right combination of size, capacity, and firmness is crucial for comfort and leak protection in the water. Your cervix height, flow intensity, and even your activity level all play a role. To measure your cervix height, simply insert a clean finger into your vagina during your period until you feel your cervix (it feels like the tip of your nose). Mark where your finger exits your body and measure the length.
| Factor | Recommendation for Swimmers |
|---|---|
| Cervix Height |
High Cervix: Longer cups work well and offer higher capacity. Low Cervix: Choose a shorter, bell-shaped cup designed for comfort. |
| Flow Intensity | Choose a cup capacity that matches your flow (e.g., small for 1-2 tampons, large for 3-4). Always empty it before swimming for maximum wear time. |
| Firmness | A medium-to-firm cup is ideal for swimming. It pops open easily, creates a stronger seal, and resists being squeezed by active pelvic floor muscles. |
Can teens use menstrual cups for swimming?
Yes, absolutely! Teens can use menstrual cups for swimming with great confidence. Many brands now create teen-specific sizes that are perfect for younger users or those with smaller bodies. These cups typically have a smaller diameter and length and are designed for a light-to-normal flow.
For teen swimmers, these cups are revolutionary. They offer long hours of protection without the worry of visible strings or having to change products between events. This allows teens to focus entirely on their sport. My advice for new users of any age is to practice at home first to build confidence before hitting the pool.
How to Practice Before Swimming
Practice is the key to perfecting your technique for swimming with a menstrual cup. By becoming skilled at insertion and removal before you take your cup for a swim, you'll feel more confident and ensure a leak-free experience.

Try inserting and removing the cup at home
Getting used to a menstrual cup takes a little time. Plan to practice for at least one or two cycles before swimming with it. The shower is an ideal practice environment for beginners, as the water acts as a natural lubricant and makes cleanup easy.
During insertion, aim the cup toward your tailbone, not straight up. The C-fold is great for beginners, but don't be afraid to try other folding techniques. To remove it, always pinch the base to break the seal before gently pulling it out. If you can't reach the base, press a finger against the side of the cup to break the suction, then carefully guide it out.
Check for a proper seal before water use
A proper seal is non-negotiable for swimming. It’s what prevents leaks and keeps water from entering the cup. Here’s how to confirm your cup has opened fully:
- Run your index finger around the base of the cup. If you feel any creases or folds, it hasn't opened completely.
- Gently rotate or swirl the cup until it opens fully.
- Give the stem a light tug. If you feel resistance, you've achieved a good suction seal.
Leaks almost always happen because the cup hasn't opened or sealed correctly. Also, ensure the tiny air holes near the rim are clear, as blocked holes can interfere with suction. With a little patience, you'll master this and be ready for confident, leak-free swimming.
Using a Menstrual Cup While Swimming
Once you've found the right cup and practiced at home, swimming with your menstrual cup is a truly freeing experience. You'll feel ready to take on the pool, ocean, or lake with confidence.

How to insert the cup before swimming
Proper insertion is everything. Always start with clean hands. To ensure no leaks, find a comfortable position like squatting, fold your cup using your preferred method, and insert it toward your lower back. Once it's in, let go and allow it to pop open. A quick rotation and a check with your finger will confirm it's sealed and ready to go.
Why you should empty the cup beforehand
From my experience, I always recommend starting with an empty cup. This simple step maximizes its collection capacity, allowing you to swim for longer without interruption. Even for a quick dip, it's a smart habit. On heavy flow days, this becomes crucial for peace of mind. Emptying the cup beforehand lets you swim for its full wear time—often up to 12 hours—without a single worry.
Pairing with Period Swimwear for Extra Confidence
Even with a perfectly inserted menstrual cup, many swimmers appreciate an extra layer of protection for complete peace of mind. High-quality period swimwear is the ultimate stylish backup solution to boost your confidence in the water.

What is Beautikini period swimwear?
Beautikini is specialized swimwear designed to be worn during your period. Our innovative swimsuits feature a built-in four-layer shield technology that provides incredible leak protection, both in and out of the water. The collection includes various styles, from leakproof swim bottoms to classic one-piece suits, all available in a wide range of women's sizes.
What sets Beautikini apart is our advanced technology that looks and feels just like regular swimwear. The four-layer system includes an ultra-soft top layer, a highly absorbent core, a waterproof membrane, and a quick-drying outer fabric. It's designed to absorb the equivalent of 3-4 tampons while neutralizing odor, keeping you fresh and confident all day long.
Using period swim bottoms with a cup
On moderate to heavy flow days, pairing period swimwear like Beautikini bottoms with your menstrual cup creates an unbeatable combination. This dual-protection strategy is ideal when:
- You're on your heaviest flow day.
- You're still building confidence with your menstrual cup.
- You'll be in the water for an extended time without easy bathroom access.
- You're participating in intense competitions or water sports.
This powerful duo effectively eliminates any anxiety about potential leaks, letting you focus solely on enjoying your swim.
Post-Swim Care and Hygiene Tips
Properly caring for your menstrual cup after water activities is essential for hygiene and extending the life of your product. Following these simple post-swim practices will keep your cup in great shape.

How to clean your cup after swimming
It's always a good idea to empty and clean your cup after swimming. If you've been in the ocean, rinsing it with fresh water is important to remove any salt residue. Likewise, after a dip in the pool, a quick rinse will wash away any chlorine. Simply clean it with drinkable water and a mild, fragrance-free soap before reinserting.
How long can you wear a menstrual cup after swimming?
Even after swimming, your menstrual cup is generally safe to wear for its usual duration (often up to 12 hours). The main reason I suggest emptying it post-swim is for optimal hygiene, not because it's likely to be full. On heavy flow days, you might empty it every 4-6 hours, but on lighter days, you can comfortably go much longer.
Your Wave of Confidence Awaits
Swimming on your period no longer has to be a source of anxiety. As we've explored, menstrual cups offer reliable, comfortable, and eco-friendly protection that's perfect for water activities. The key is finding the right cup, mastering the insertion to get a leak-proof seal, and practicing until it feels like second nature.
For those days when you want ultimate peace of mind, combining your cup with the backup protection of Beautikini period swimwear creates an unstoppable team. This strategy is my personal recommendation for heavy flow days or high-stakes competitions, ensuring your focus remains entirely on your performance and enjoyment.
You now have the knowledge to join the thousands of swimmers who have discovered this game-changing freedom. Embrace the confidence that comes with gear that truly performs. Your worry-free swim is just a cup away.

Frequently Asked Questions
Q1: Can I swim confidently with a menstrual cup?
Yes, absolutely! When inserted correctly, a menstrual cup forms a secure suction seal with your vaginal walls, providing reliable, leak-free protection. This makes it an ideal solution for swimming, allowing you to enjoy the water without worrying about leaks or frequent changes.
Q2: How do I ensure my menstrual cup doesn't leak while swimming?
The key to preventing leaks is ensuring a proper seal. Before you swim, empty the cup, re-insert it, and then check the seal by running your finger around the base and gently tugging the stem. If you feel resistance, you've created the necessary suction to prevent water from getting in and blood from getting out.
Q3: Will a menstrual cup fill with water when I swim?
No, a properly sealed menstrual cup will not fill with water. The same suction that keeps your menstrual fluid contained also effectively blocks water from entering the cup. This is why it’s such a reliable choice for swimming in pools, lakes, and the ocean.
Q4: Is it safe for teens to use menstrual cups for swimming?
Yes, it's perfectly safe. Many brands now offer teen-specific sizes that are smaller and designed for a comfortable fit for younger or more petite users. They provide hours of leak-free protection, empowering teens to participate in all water activities without period-related limitations.
Q5: Should I pair period swimwear with my menstrual cup for extra security?
While a well-fitted menstrual cup is very reliable on its own, pairing it with period swimwear like Beautikini's is an excellent idea for maximum peace of mind. This combination is perfect for heavy flow days, intense water sports, or when you’re still building confidence with your cup. It provides an extra layer of backup protection so you can feel completely worry-free.
Q6: What's the best way to change a menstrual cup in a public restroom at the pool?
It's easier than you think! The simplest method is to bring a small water bottle into the stall with you to rinse the cup over the toilet. Alternatively, you can wipe it clean with toilet paper before reinserting. If available, using an accessible or family restroom with a private sink is also a great option.
