Can You Swim On Your Period? Your Ultimate Guide

Has this ever happened to you?

Your period arrives – right before a pool party, beach trip, or long-awaited vacation – and suddenly, everything feels... complicated.

Whether you're a teen navigating your first cycle or a mom packing for your kid’s camp week, one question always seems to pop up:

Can you actually swim on your period – without stress, leaks, or awkward moments?

The short answer? Yes, absolutely.

And we’d know – because at Ruby Love, we invented period swimwear. Literally. Our patented designs were created to solve exactly this problem: how to stay confident, comfortable, and protected in (and out of) the water, no tampons required.

Of course, period swimwear isn’t your only option – and if you're weighing tampons, pads, or other solutions, we’ve broken it all down for you before right here. 

But today, we’re talking about everything you need to know when your period and swimming plans collide.

From debunking myths to avoiding those worst-case "what if" moments, consider this your go-to guide for swimming on your period – backed by the people who pioneered how to do it better.

Period and Swimming: Yes, You Can Get In The Pool On Your Period

First things first:

Your period doesn’t come with a “no swimming” rule.

It just doesn’t. Get that out of your mind!

From swim meets to spontaneous beach days, having your cycle shouldn’t sideline you – or your friend, your daughter, or anyone who has periods.

“Your period isn’t a reason to miss out on swimming, camp, or just feeling confident in your own skin.” — Crystal Etienne, Founder & CEO, Ruby Love

But that doesn’t mean navigating your period and your swim plans at the same time is easy.

For one thing, there’s a world of weird myths that we (as in, all of us) have bought into, at one point or another, around periods and swimming.

Let’s see if you’ve heard any of these…

Myth #1: Your Period Simply Stops in Water

Not quite. (Though that’d be nice, wouldn’t it?) 

Water pressure might slow your flow while you’re submerged, which can make it seem like your period is taking a break. But it doesn’t magically "turn off" your period.

The moment you step out of the pool, gravity will kick back in and you’ll be in need of protection, quick.

Myth #2: Swimming on Your Period Attracts Sharks

Nope, this one’s fully a myth. 

We promise sharks aren’t syncing with your cycle. 

There’s zero scientific evidence that menstruating swimmers are more likely to attract sharks. You’re far more likely to get a sunburn than a shark encounter. 

So pack sunscreen, not shark repellent, and swim worry-free.

Myth #3: You Can’t Swim Without a Tampon

If you’re on your period, tampons aren’t your only ticket into the pool.

You’ve got options. 

And that’s a good thing, since tampons just don’t work for everyone. 
 
There are plenty of ways to stay protected – cups, disks, teen period swimwear – that work without needing to master tampon insertion first.

Myth #4: You’ll Leave a Trail of Blood in the Pool

Nope.

Thanks to water pressure (remember, it temporarily holds things in while you're submerged), you’re not about to turn the pool into a crime scene lookalike.

But – the moment you step out of the water? That’s when leaks can happen... if you’re not wearing the right protection.

That’s exactly why Ruby Love’s patented period swimwear exists.

With built-in absorbent layers and water-resistant (not waterproof) technology, it’s designed to catch those post-swim surprises – without puffing up, shifting, or letting anything slip.

So you can towel off, lounge, or make that walk back to your chair without a second thought.

Myth #5: Pads Work Fine If You Stay in Shallow Water

We get it! Pads feel like a safe, familiar option.

But in the pool, they’re anything but.

Pads soak up water instantly, swell uncomfortably, and can shift or even peek out. Whether you’re ankle-deep or fully doing laps, pads and pools just don’t mix.

The Ultimate "What If?" Guide: Tackling Poolside Anxiety (For You AND Your Overthinking Brain)

Let’s be honest, here.

Menstruation and swimming aren’t really the problem.

It’s the mental gymnastics that happen before you even touch the water.

If you (or your daughter) are running through every worst-case scenario, don’t worry. You’re not being dramatic. You’re being prepared.

And lucky for you, we’ve been there.

And we know how to turn those “what if?” moments into “so what?” confidence.

What If My Tampon Falls Out While I’m Swimming?

Classic worry – but here’s the truth:

If you’re wondering, “Can a tampon fall out while swimming?”, the answer is almost never.

Tampons are designed to stay put, thanks to your body’s natural structure – not superhuman muscle strength. Once it’s inserted correctly, you’re good to swim, splash, and dive without fear of it slipping out.

That said, tampons aren’t flawless. 

They can still absorb pool water (yep, even through the string), which can lead to discomfort or leaks after you’re out of the water.

So if the idea of soggy strings or surprise leaks is adding to your stress, that’s your cue to try period swimwear, which has no internal products, no strings, nothing to “fall out” in the first place.

What If My Tampon Absorbs Pool Water and Leaks?

Tampons do absorb water while swimming. They can’t tell the difference between your flow and the pool. 

If you do decide to use a tampon, that’s fine! 

Just know that, to be as comfortable as possible, you’ll need to bring a backup or two so you can swap it out when it gets full.

What If I Forget I’m Wearing a Tampon and Stay in Too Long?

We’ve all lost track of time doing cannonballs.

But yeah, leaving a waterlogged tampon in for hours is an irritation risk and could even be dangerous, if you let it go all day. 

Set a timer on your phone for a few hours, if you can. Keep a tampon in your poolside bag or otherwise right next to you, so when you naturally have to go to the bathroom or freshen up, your replacement tampons are right there.

(Or, if you’re truly worried about forgetting, you could always consider an option that doesn’t need refreshing, like period swimwear…)

What If I’m Swimming With a Period Pad and It…Floats?

Listen, we get it. Desperate times, desperate measures.

But swimming with a period pad is really, really not your best option. 

Pads aren’t made for pools. They’ll soak, swell, and possibly try to make a break for it.

If you’re poolside and just dipping your toes? Maybe.

But if you’re planning to actually swim? Just don’t do it.

What If I Start My Period in the Pool and Don’t Notice?

First, you’ll notice.

Second, even if you don’t, water pressure keeps things in check while you’re submerged.

The real moment to watch for is when you get out.

That’s why having the right protection (like effective, stylish period swimwear) matters more than timing.

What If I Have Cramps Halfway Through Swimming?

Here’s some good news for you: 

Swimming can actually help cramps. 

But if they hit mid-swim, and moving suddenly feels awful, take a break. Find a place to lounge by the pool. 

And, if your cramps get really bad, make sure to pack some ibuprofen in that “just in case” kit. (More on that in a moment.)

What if Someone Sees My Tampon String?

Real talk?

If they do, so what! 

But if it’s going to live rent-free in your head, tuck the string neatly inside of yourself before you suit up.

Your Pool Day, Period or Not: A Confidence Timeline

Feeling good isn’t luck. It’s knowing you’ve got every “what if” handled.

Here’s how we’d recommend prepping for your pool day if you have a sneaking suspicion that your period just may drop on by.

Before You Leave the House: Prep for Period and Swimming Success

Check the calendar before you leave (...but don’t rely on that alone).

Menstrual cycles have a sneaky way of showing up unplanned, right before a beach trip or pool party. 

Even if you're not sure you're getting your period, swimming without a tampon – or without any prep in your backpack or purse – can turn stressful fast. Have your essentials ready to go, regardless. 

Which, speaking of:

Pack your “just in case” kit

Swimming with peace of mind is all about preparation. 

If you can, pack the following: 

▪ A backup tampon (because yes, you can swim with a tampon in, but you’ll want a fresh one after). Also, a friend might be in need and you’ll be able to come to the rescue.

▪ Wipes and a liner for post-pool comfort.

▪ Extra swim bottoms – especially if you’re using period swimwear.

▪ Pain relief, because cramps don’t care about your schedule.

Psst: Whether you’re looking for kit inspo or want a few extra fun (and helpful!) items to add to yours, we’ve got something for you to check out – we partnered with Teen Vogue to create a Period Essentials Kit. See what it’s got right here!

In the Locker Room (or Bathroom): Last-Minute Checks

Start with a bathroom visit and make a plan to head back (often). 

If you're using a tampon, remember: Tampons can absorb pool water along with your flow. 

So if you're wondering, “Can I use the same tampon after swimming?” – the answer is no. Change it after every swim session.

Tuck the tampon string if you’re worried about it

Worried about whether it’s safe to wear a tampon in the pool and avoid any string mishaps? 

You’re good – just tuck it neatly for extra confidence.

Poolside: Can You Go Swimming On Your Period Without Stress?

Yes! You can get in the pool on your period (period).

Whether you’re using a tampon, swimming with a period pad (not ideal), or rocking leak-proof swimwear, remember this: 

You belong in the water just as much as anyone else.

Keep moving. It helps!

Light activity like swimming can actually ease menstrual cramps.

So if you’re feeling sluggish thanks to PMS, a few laps might be just what you need.

Post-Swim: Smart Moves After Menstruation and Swimming

Change out of your wet gear ASAP once you’re done swimming.

No matter what type of period gear you’re using, don’t lounge too long in damp clothes. 

Especially since tampons soak up pool water – and that won’t exactly feel good once you’re no longer in the pool.

Surprise! Let’s Say Your Period Shows Up Mid-Swim

Didn’t think you'd be swimming with your period today?

And you’ve found yourself, uh, less than prepared?

This happens to everyone. It’s awkward and frustrating, but it doesn’t have to ruin your day – or even your swimming plans.

Start by asking around. If you feel comfortable asking your friends or a trusted older adult (a friend’s mom, for example) if they have supplies, do so.

You can also go ask a lifeguard or staff to see if they have emergency female hygiene supplies on hand, too. Use that wording, and ask it matter-of-factly. If it helps, you can pretend you’re asking for a friend, but – trust us on this:

They will not care.

If you’re able to find the supplies you need, great! Go change and continue with your day.

If not, stick to socializing in the sun until you can grab proper protection.
