How to make your menstrual cup pop open

Is your menstrual cup leaking or not popping open? Menstrual cups make life 1000% percent easier when you’re on your period, but figuring out how to use them can take a little time. The #1 secret to a leak-free period with a menstrual cup? Making your menstrual cup pop open.

If you are lazy, here is a short video for you!

Getting your menstrual cup to pop open correctly will allow it to form a tight seal so that you won’t experience any unwanted leaking. Today, we’re going to share some helpful tips to make sure your cup opens up perfectly every time.

While the cup itself is designed to be leak-free, it can take a few tries to get comfortable using and inserting it. We recommend that you practice at home first (rather than in a public restroom) so you can learn the perfect cup technique that works for you. You may even want to practice inserting your cup when you don’t have your period. If you do, don’t leave the cup in — just get familiar with how it feels when it’s inserted properly and forming a seal, and then remove the cup.

Why won’t my menstrual cup pop open?

There are a few different factors that could be preventing your cup from fully opening. It could simply be a matter of finding a fold that works well for you, or you could actually need a different cup.

First, grab some lube

If you aren’t already using lube when inserting your cup, this is a must! Our Pixie Lube is designed specifically to provide a smooth insertion and a good seal for your menstrual cup. Not only does it make inserting your cup easier, it will help you position your cup correctly so that it can form a seal and prevent leaks. For many cup users, using a little bit of lube is all it takes to get their cup to pop right into place.

3 easy steps to make your menstrual cup pop open

Now, let’s make sure you’re inserting the cup properly. Before inserting your cup, always wash your hands thoroughly. And, try to relax! This process can feel intimidating to new cup users, but if you’re feeling tense, it will make inserting your cup harder. So take a few deep breaths and remember, while learning how to use a menstrual cup can be a little uncomfortable at first, it should never be painful, and the cup can’t get lost inside you. So there’s nothing to worry about!

  1. Use the C-fold for insertion

    The C-fold is a simple fold that you can do with one hand, and that allows the cup to pop open easily.

  2. Run a finger around the rim

    After your cup is fully inserted, run a clean finger around the rim of the cup (the top). As you do, you may feel some folds or indentations.

  3. Grab the base and twist

    If you feel folds, grab the base of the cup and gently twist the cup in a circular motion. Turn the cup one full rotation. This will help it pop open and form a seal.

That’s it! For most people, following these steps will allow their cup to pop open properly and provide leak-free protection!

Why is my cup still leaking?

If you’ve tried these steps and your cup is still leaking, there are a few possible reasons:

  1. Your cup could be the wrong size. If your cup slides up or down a lot during the day (a little movement is totally normal… we’re talking a LOT of movement) you might have the wrong cup size. Pixie Cup is available in two different styles and three sizes, so we have options for just about everyone!
  1. Your menstrual flow could be heavier than your cup can handle. We designed the Pixie Cup in a bell shape to capture as much fluid as possible — more than several tampons. But, if you have an especially heavy period, you may need to empty your cup more often. If you don’t want to deal with the hassle of emptying your cup every few hours, try our XL Pixie Cup! No matter what size you wear, make sure you empty and clean your cup at least every 12 hours to keep it clean and sanitary.
  2. You might have a tilted cervix. If you have a tilted cervix, and your cup isn’t properly aligned, your menstrual flow might run along the vaginal wall, missing the rim of your cup completely. If this is the case, try wearing your cup lower. You may also want to try our Pixie Cup Slim, which was specially designed for people with a tilted or low cervix.
  3. You may need a cup made with a firmer material. Some people find that it’s easier to get their cup to pop open when they use one that’s slightly more rigid. If you’re using a cup that’s very soft and flexible, try one that’s more firm, such as our original Pixie Cup.

Menstrual cups take a little bit of practice, but don’t let that scare you. Everyone’s body is different, and everyone uses a slightly different technique. Before long, you’ll figure out which folds and tricks work for your body. Once you’re comfortable using a cup, you’ll never go back to pads and tampons!

Which Pixie Cup is right for me?

Which Pixie Cup is right for me?


which menstrual cup is best for me

It’s hard enough to try to find the perfect pair of shoes to go with your outfit… and you’re supposed to decide which menstrual cup is best for you without trying one on? That’s crazy!! 

We get it! Don’t worry, we’re here to make sure you have all the information you need to figure out which of our menstrual cups is best for you!

Which menstrual cup is the best?

There is really no one answer to this question. Everyone’s body and cycle is different, so what works for your bestie might not work for you. That’s why we’ve created several different versions of our Pixie Cup! Factors such as how heavy your flow is, the position of your cervix, your age, and whether you’ve given birth all play a role in how your menstrual cup will fit and feel when it’s in your body.

There are a few things to consider when you’re choosing a Pixie Cup, so make sure you review all of the factors listed below:

Flow (go with it!)

  • Light or regular flow: If you have a lighter flow and use just a pad, or tampons between light and regular, you will likely be just fine with a size small in either our regular Pixie Cup, or the Pixie Cup Slim.
  • Heavy flow: If you are grabbing a Super tampon on your heavier days, you will probably be a better fit with our Large Pixie Cup or Large Pixie Cup Slim.
  • Very heavy flow: If you’re going through multiple Super Plus or Ultra tampons per heavy day, you might want to give our XL Pixie Cup a try!

Keep in mind you don’t have to choose just one. If your flow fluctuates during your cycle, you may want to try our Pixie Cup combo pack! Use the large on heavier days and the small when your flow is lighter.

Cervix height

  • Average or high cervix: Are you able to use a larger tampon without pain “up there”? Can you touch your cervix with your finger? (Your cervix is round and about the texture of the end of your nose.) If you have a higher cervix, you should be able to use any of our Pixie Cup sizes with no problems.
  • Low cervix: Is your cervix easy to reach, especially during your period? Do you ever experience pain when inserting a tampon? If so, you might want to start with a smaller size Pixie Cup. We recommend the Small Pixie Cup Slim, which is a little more flexible.

Other factors

  • If you have trouble inserting a tampon, or you are under the age of 18, you might want to start out with one of our smaller Pixie Cups.
  • If you have no trouble inserting larger sized tampons, with a little practice you should be able to easily choose any of our Pixie Cup sizes.
  • If you have given birth to a child vaginally, your body will likely be able to fit any of our Pixie Cup sizes.

Still not sure? Take a look at some of these frequently asked menstrual cup questions, or take our menstrual cup quiz! And don’t worry if all of this seems overwhelming at first. If you’re brand new to menstrual cups, it may take a little while to get the hang of everything. We’re here to help! Feel free to contact us and we’ll be happy to answer any questions! And, if you buy a Pixie Cup and you aren’t totally happy with it, we’ll give you a full refund! Your happiness is our priority.

Which menstrual cup is the softest?

We created our Pixie Cup Slim with a softer, more pliable silicone. While many people do fine with our regular Pixie Cup, the Slim is a great choice for younger girls or first-time cup users because it is gentler and easier to fold. We’ve also found it to be a great option for anyone with a tilted uterus or lower cervix.

Which menstrual cup leaks the least?

Again, there is no one answer to this question. The key to avoiding menstrual cup leaks is using a cup that’s the right size for your body and achieving a good seal. Leaks are almost always due to an issue with the cup position, size, or seal. If you’re a new cup user, it may take a few cycles to become comfortable inserting your cup and achieving a proper seal.

If your cup is leaking because it’s too small for you, try a larger size. Somewhat surprisingly, using a cup that is too big is also a common cause of leaks. If your cup is too big, it won’t be able to fully pop open

Which menstrual cup is the smallest?

Our Pixie Teen Cup is our smallest menstrual cup, which makes it great for lighter flow and younger users. Our Pixie Teen Cup is 1.5 inches in diameter and holds 18ml of fluid. By comparison, our regular small Pixie Cup holds 25ml of fluid and is 1.68 inches in diameter.

How much does a Pixie Cup hold? 

The Pixie Cup is available in several different styles and sizes, holding between 20ml and 35ml of fluid. For comparison, a tampon holds about 5ml of fluid when it’s completely maxed out. Our smallest cup, the small Pixie Cup Slim, holds 20ml and is the equivalent of 4 tampons. Our largest cup, the Pixie Cup XL, holds 35ml, or the equivalent of 7 tampons.

XL: 35ml

Which menstrual cup holds the most fluid?

For people with a very heavy flow, we created our XL Pixie Cup. It holds 35ml of fluid, which is roughly the equivalent of 7 tampons. While all of our cups are safe to use for up to 12 hours, people with a very heavy flow may need to empty their cup sooner to avoid leaks. This is perfectly normal. Just like tampons, a menstrual cup is effective for different amounts of time for different people.

Which menstrual cup is best for beginners?

For beginners and younger users, we recommend our Pixie Teen Cup. Made from medical-grade silicone, with petite anatomy in mind, the Pixie Teen Cup is our smallest cup. It’s just soft enough to move and flex with your body when swimming or playing sports, and just firm enough to easily pop open and seal for first-time cup users!

We also recommend using a menstrual cup lubricant every time you insert your menstrual cup to make insertion smooth and pain free.

Which menstrual cup is best for virgins?

If you’re a virgin interested in using a menstrual cup, we advise you to start with a smaller cup and apply a little lubricant. You may want to try our Pixie Cup Slim, which is made from a softer material. Learn more about using a menstrual cup as a virgin.

Why does my menstrual cup slip down when I use it for a while?

Why does my menstrual cup slip down when I use it for a while?

There are so many things to think about when you are using a menstrual cup for the first time.

You have to adjust to the process of emptying your cup, learn how to keep it clean and sanitized, and figure out where you want to store it! There is often a learning curve, but once you get the hang of it, using a Pixie Cup becomes second nature!

If you don’t have a Pixie Cup yet, you may be freaking out as you read through the blog. There is a LOT of information here about cups and that can be intimidating! Our advice to you is, go ahead and give it a try! The worst thing that can happen is it doesn’t work for you… and we stand behind our products 100% with a leak-free guarantee so you don’t have to worry about a thing!

Plus, if you have any questions at all, drop them in the comments either on the blog or on social media, or send us an email! We would be happy to help you to find the answers… and we might even write a blog post about it!

So, the question we are addressing today, and it’s one we get all the time, is this:

Why does my cup slide down when I use it for a while?

There are several reasons why this could be the case. First, you’ll need to think through a couple of questions.

Does it cause irritation?

Does your cup irritate you when it slides lower? If not, this isn’t really an issue. It’s completely normal for your cup to move up and down a little inside your vagina, and find a place to settle comfortably. As long as this is just a minor movement and doesn’t cause any irritation to you, it’s nothing to worry about.

Has your cup ever fallen out?

If your cup has dropped so low that it is close to or has fallen out, you might be using the wrong cup size. We offer cup sizes from small to XL and several different styles of cups, so you might want to size up. Everyone’s body is so different, which is why we include a variety of options!

Is your cup leaking?

If your cup isn’t causing any irritation but you are experiencing leaking when it moves, this could also be a sign that your cup is a size too small. Go ahead and size up to a larger cup size and see if that works better!

Remember, if your cup doesn’t fit quite right, send us a message and we’ll switch it out for a different option, or give you a full refund!
