Menstrual Cup Leaking Help: Don’t Give Up too Soon!

Menstrual Cup Leaking Help

Many women who use a menstrual cup for the first few cycles wonder why it keeps leaking. They usually feel frustrated that they have to wear pads when they thought those days were over forever. Pro Tip: It’s less terrible to wear pads as a back-up if you have reusable cloth ones!

Anyway, the leaking is indeed terrible. This is especially the case when our friends and family members tell us how amazing their menstrual cup is!

While some menstrual cups simply don’t fit a certain body shape (see this menstrual cup comparison chart for help) and a new model or size of cup should be tried, it’s most often a problem related to insertion.

Here’s some advice for menstrual cup leaking help:

Menstrual Cups: The Pop

When you insert your menstrual cup, be sure it pops open. With some of the stiffer cups like the MoonCup or the Diva Cup, you’ll know exactly what I mean. You fold it, insert it and then it’ll most often just open it by itself when inside you.

For some of the softer menstrual cups like the Anigan EvaCup, or the Iris Cup, it’ll be a bit more difficult to get them to pop open and you might have to “assist” them. Here’s how:

Run your finger around the edges of it to make sure it’s round, with no flat parts. It should be shaped like a circle in your vaginal canal, with no flat or folded parts. Another way to do this is to grab the menstrual cup firmly by the stem and twist it a turn each way to ensure it’s secure. This helps your cup make a strong seal with your body. Your period cup needs to suction to your vaginal walls in order to make sure it seals and doesn’t leak. Doing either of these two things will ensure that.

Menstrual Cup Leaking Help: Find your Cervix

Your cervix is where the fluid actually flows from, not your vaginal wall. In some cases, it’s possible to suction the cup to the wrong place, leaving space for fluid to flow past your menstrual cup. In order to prevent this, try to insert your menstrual cup horizontally, towards your tailbone and not upwards. I struggled for a few cycles when I first started using the Diva Cup because I wasn’t pointing the cup in the right direction. If you’re sitting down when you’re inserting your Menstrual Cup, point it back towards your tailbone.

A helpful tip is to find your cervix. If it’s medium-low in your vaginal canal, you should be able to reach it with your fingers. If it’s very high, you might not be able to. But, it’s still good practice to explore around in there and figure out what everything. Knowledge of your lady parts will certainly help you with menstrual cup insertion.

Here’s how you can find out where your cervix is:

The Wrong Size Menstrual Cup?

Check this menstrual cup comparison chart for some ideas of cups that will work well for you. Most menstrual cups have two sizes: Small and Large. Small ones are roughly for women under 30, smaller women, or those that haven’t given birth vaginally. Larger ones are roughly for women over 30, larger women, or for those who’ve given birth vaginally.

But of course, each women’s body is different and there’s no hard and fast rule about this. You’ll have to experiment to see what works best for you if your menstrual cup is leaking. It could be simply a matter of trying a different brand, or it could be a matter of trying a different size. You won’t really know until you try a few different ones.

Menstrual Cup Leaking Help: Empty it More Often

Some menstrual cups have a lower capacity than others and you may have to empty it before the recommended time period on your heaviest flow days. In some cases, it can be every 4-6 hours if your flow is extremely heavy. Fluid can definitely leak out of your menstrual cup if it’s filled to capacity.

If you have a very heavy flow, consider one of the cups with larger capacities such as the Anigan EvaCup or the Meluna Cup. An average cup has a capacity of 30ml. More than this could be considered a high-capacity one. Less than this would be considered low-capacity and not really suitable if you have a heavy flow.

Try a Different Cup

The Diva Cup is the most popular menstrual cup in the world and for good reason: it’s made from extremely high quality silicone and it’s affordable. It’s often the first menstrual cup women try and most of the other are compared against this standard. You can easily get this popular menstrual cup on Amazon today:


However, the Diva Cup is quite stiff and won’t work for some women. Although it pops open easily for most women, it simply doesn’t for a few, for whatever reason. Many people who experienced leaking with the Diva cup have switched to the Lunette or the Dutchess Cup and had good results. Both of these are top-quality menstrual cups, but the design, as well as the thickness and flexibility of the cups are slightly different.

    I love, love, love my Cup. At first I had a problem with leaking, but I turned my cup inside out and for some reason that worked for me. Mine use to leek all the time but after a lot of online searching I found someone with the same issue. Good luck. It’s always most difficult during that learning period.

  2. Flo

    I’ve been using the diva cup for 6 years now and was always super happy with it, but in the last months it seems to be leaking because it doesn’t ”pop” anymore. I have read that another factor for that is the general musculation; if you train a lot and your body is muscular, chances are your vagina will be too. I do a looooot of physical activity, more in the last year than in the last 6, and I wonder if it is related, since my core muscles and pretty much all of my body really is so toned, I read that the cup material can be not strong enough against those muscles. Melune have the ”sporty cups”, but they don’t ship to Canada.. Anyways, thanks for your website, sooo many informations, and I wanted to share about the muscular thing, since it isn’t discussed in this post!
