It can often be quite confusing and even intimidating when you come across a situation where the menstrual cup just won’t open.
It’s one of those common issues that not many people talk about, but it does happen every now and then.
We will explain why your menstrual cup isn’t opening up properly, as well as provide you with simple solutions to help get things back in motion.
Why Menstrual Cup Won’t Open?
First-time menstrual cup users or even experienced ones may sometimes encounter difficulties when it comes to getting the cup to open properly inside the vagina.
This issue can be frustrating and for a few reasons very uncomfortable, but understanding the common reasons behind it can help you find a solution that works for you.
Folding Technique
One of the primary reasons for a menstrual cup not opening is the incorrect folding technique.
There are several ways to fold a menstrual cup before insertion, such as C-fold, punch-down fold, or 7-fold.
It’s crucial to find one cup that suits your anatomy and practice until you get comfortable with it.
The right folding and insert technique will ensure that the cup unfolds correctly once fully inserted into your vaginal canal.

Size and Firmness
Another factor that may contribute to this problem is selecting an inappropriate size or firmness level of your menstrual cup based on your needs and body type.
Cups come in various sizes and firmness levels designed for different age groups or those who have given birth vaginally versus those who haven’t.
Choosing one too small may prevent it from creating an adequate seal against vaginal walls; conversely, if it’s a too firm cup, you might experience discomfort while inserting it.
Cervix Position
The position of your cervix also plays a significant role in how well the menstrual cup opens up after insertion.
A low cervix might cause interference with the proper placement and unfolding of the cup inside your vagina.
If positioned too high above the pubic bone could lead to similar issues in maintaining an effective seal against menstrual cup leaks.
Inadequate Lubrication
Inadequate lubrication during insertion is another common reason why some people struggle with their menstrual cups not opening correctly upon placement into the vaginal canal.
What to Do When Menstrual Cup Doesn’t Pop Open
Here is some guidance to keep in mind to ensure your menstrual cup pops open every time.
Position Yourself
When inserting the folded cup into your vagina, aim it towards your tailbone rather than straight up.
This helps in positioning the cup correctly around your cervix and allows enough room for it to open fully once inside.
After, gently twist and rotate the cup, or wiggle the base of the cup while holding onto its stem – this ensures that it unfolds completely and creates a secure seal against your vaginal walls preventing any blood leaking from menstrual cup.
If you don’t feel the cup spring open, run your clean finger in a circular motion around the cup’s rim.
Understand Your Anatomy
It is also important to note that each woman’s anatomy is different.
Finding the right size of menstrual cup plays a significant role in getting the cup to pop open.
If you’re unsure about which size is suitable for you or if you have encountered issues with leaking or popping open despite following the proper insertion techniques mentioned above, then consider trying out a new cup in another size until you find one that fits comfortably without causing any discomfort.
Proper Maintenance
Bear in mind that regular maintenance after each use also contributes significantly towards avoiding leakage and opening problems during menstruation.
Taking care of the menstrual cup by cleaning, sterilizing, and storing properly will prolong its lifespan and help maintain its functionality.
Try Different Techniques
There are multiple ways to fold a menstrual cup before insertion, such as the C-fold or punch-down fold.
Experiment with different folds and techniques until you find one that works best for you.
Use Lubrication
If you’re experiencing difficulty inserting your cup or getting it to pop open fully in your vaginal canal, try using a water-based lubricant on both the rim of the cup and around its sides before inserting it again.
Or rinse it in cold water prior so the cup slides in smoothly and sits nicely against the vaginal wall.
Find the Right Size and Shape
It is crucial to ensure you’re using the correct size and type of menstrual cup for your body’s unique shape and flow needs.
Different brands offer various-sized period cups (usually small, medium, or large) as well as different firmness levels.
Choosing the right combination for you will make a significant difference in how easily your period cup opens.

Choosing the Right Size and Shape of a Period Cup
Various factors come into play when selecting an ideal menstrual cup, such as your age, whether you’ve given birth vaginally or not, and even the position of your cervix.
It’s essential to consider these aspects because using an ill-fitting cup can lead to issues like leakage or difficulty in insertion and removal.
Conclusion
If your menstrual cup isn’t opening properly, make sure to consider the many factors that may impact your experience.
These include incorrect folding technique, selecting the wrong size or firmness, having a low or high cervix, inadequate lubrication and understanding your anatomy.
Remember to take the time to experiment with different techniques and find the perfect fit for your own body and preferences.
The C-fold is often a popular starting point, however, whatever works best for you is key.
With patience, perseverance, and understanding of your own body – it’s possible to find the perfect fit for a menstrual cup.
