Which Menstrual Cup is Right for Me?

One of the questions we get most often is "Which cup should I buy?" or "Which cup is most suitable for me?" For first-time cup users, it may seem like a daunting task to wade through the plethora of information on the different cups available on the Internet. However, do keep in mind that most cups are relative similar, so there is no need to over-analyse and stress out over the options available.

Below are some considerations to keep in mind when choosing your cup. All our listings include the necessary information required for you to make the right choice.

Amount of Flow

A bigger cup, with a higher capacity, is more suitable for someone with a heavier flow. A smaller cup is more suitable for someone with a lighter flow.

Many think that they have heavy flow, but in reality, the average woman has a moderate flow with studies showing a range of 30-120 ml (or 2-8 tablespoons) for their entire period. If you currently use tampons, you can estimate your flow based on the number of tampons used per period and the tampons' capacity.


A smaller cup is recommended for young women who have not experienced sexual intercourse yet. As the vaginal muscles are tighter, a smaller cup is easier to insert.

For women who have experienced a vaginal birth, a larger cup is recommended as childbirth changes the vaginal muscles, the shape of the vagina, and hipbone structure. 

Location of Your Cervix

Wash your hands well, and see if you can reach your cervix during menstruation. It is usually located on the left side of the vaginal wall (when you touch it, it may feel like the end of your nose, a "slimy donut" or even a tiny penis).

If your cervix sits low (measured to your first knuckle), a shorter cup is recommended, as it will fit more comfortably inside your vagina. A low cervix can be touched very easily.

If you have a cervix that is easy to reach but not extremely low (around your second knuckle), most lengths of cups should be suitable.

If your cervix is hard to reach or you are unable to reach it at all, your cervix is high and you may prefer a longer cup.

Stiffness of Cup

In general, larger cups are slightly firmer than their counterparts. A firm cup will pop open more easily. but may cause discomfort due to the pressure from the stiffness. A soft cup is easier to fold and insert.

Sports that strengthen the core muscles like Yoga and Pilates have a strengthening effect creating very strong vaginal muscles. If you have an active lifestyle, a stiffer cup may prevent your muscles from crushing the cup.

If you have a sensitive bladder, a softer cup may be more suitable for you.

In conclusion, all women are different and the above are just guidelines and recommendations to help you make an informed choice. Although most manufacturers suggest that women under 30 who have never had a vaginal birth should wear the smaller size they offer, and women over 30 or who have had a vaginal birth should wear the larger size, do keep in mind that these are merely guidelines. For example, if you are over 30 and have children, you may still have a strong pelvic floor if you are active, and you may feel more comfortable in a smaller cup. Know your body and make a decision based on that alongside the manufacturer’s suggestions.

How Do I Use a Menstrual Cup?

Inserting a menstrual cup is similar to inserting a tampon. First, wash your hands.

Then, fold your menstrual cup to make it smaller.

While squatting or standing with one foot on the floor and the other on a toilet or bath tub, slowly push the folded cup into your vagina. This should be done at about a 45 degree angle as your vagina is angled and not straight-up inside your body.

The cup should pop open and unfold inside your vagina, which creates a light seal against the vaginal walls. Make sure the cup is unfolded so blood does not seep out around it. You can check by running one finger around the base - it should be round or oval. If the cup does not feel like it has opened fully, grab the stem and give the cup a small turn, which should usually do the trick.

If correctly inserted, the cup should not leak or cause any discomfort, as with a tampon. Push it in until you're comfortable; this depends on how low your cervix is, which varies from person to person. The cup can be worn low in the vagina. During the course of the day, the cup may migrate upwards and sit against the cervix. The cup can be worn up to 12 hours, depending on your flow.

The stem on the bottom of the cup can be used to find your cup when you want to remove it. (The stem can be trimmed down to whatever length you're most comfortable with.)  Simply pulling on the stem is not recommended to remove the cup, as pulling it down will create suction. Reach up to the stem of the cup in order to find the base. Using your index finger and thumb, pinch the base to release the seal. Gently and slowly ease the cup out of your vagina. Empty the contents of the cup, rinse/wipe and reinsert.

When your period is over, wash your cup thoroughly and store it in its bag for proper ventilation. Never store the cup in an airtight plastic container or bag.

Why Switch to a Menstrual Cup?

Menstrual cups...

... don't dry you out or disrupt pH levels

Pads create a stifling, moist environment which is ground zero for yeast infections, bacteria and odour. Tampons aren't great for you as well; other than absorbing your menstrual fluid, they also absorb the natural moisture produced by your vagina. This creates an imbalance of moisture and affects the pH levels of your vagina. However, a menstrual cup does not absorb, but rather collects the menstrual fluid to be emptied later. Therefore, the natural fluids produced by your vagina do not get absorbed, and you don't feel uncomfortable and dry.

... are comfortable

Correctly inserted, a menstrual cup is so comfortable that you won't even notice it’s there. It may take a little practice at first to find the angle and position that is right for you. Once you get the hang of inserting the menstrual cup, you will be amazed at how easy it is to use. Say byebye to bulky, uncomfortable pads!

... can go longer between changes

Menstrual cups have a greater capacity than even the most absorbent tampon, so you can go longer between emptying your cup! Menstrual cups can be worn for up to 12 hours (depending on your flow). This means less worrying about changing your pad/tampon every few hours for fear of leakage.

... are better for the environment

The average woman throws away around 125-150 kg of tampons, pads and applicators in her lifetime. Can you imagine the sheer amount of waste created? Unlike pads and tampons, menstrual cups are reusable and should last for several years with proper care. Since you can reuse them every period, there is less waste created to clog up our landfills or improperly disposed of in toilets to block up our sewage systems. Menstrual cups are not just good for your body; it's also good for our planet!

... are convenient

Menstrual cups can be used no matter what physical activities you've planned for the day: doing sports, yoga, dancing, swimming, snorkelling, scuba diving, biking, hiking, camping, travelling, and many more! You no longer have to lug around extra pads or tampons, or worry about leaking. Furthermore, cups are great for people who work long hours or have few chances for toilet breaks! Isn't it great not having to worry about your period?

... are cheaper in the long run

The cost of purchasing a menstrual cup is a one-time cost upfront, which provides you with years of use if you properly take care of it. Compare that to buying a pack of pads or tampons every month. The cup will pay for itself within the first couple of months, and you no longer have to worry about having enough supplies when your period is nearing every month.
