What medium flow needs from a menstrual cup
For individuals experiencing a medium menstrual flow, selecting the right menstrual cup involves balancing capacity, comfort, and ease of use. A medium flow typically means changing a cup every 6-10 hours, so the cup’s capacity should align with this duration without requiring excessive emptying. Cups with a capacity between 20-25ml are generally suitable, providing ample containment for several hours of wear. Comfort is paramount, as a cup that is too firm can cause pressure, while one that is too soft might not fully open, leading to leaks. A medium firmness is often ideal, offering sufficient structure to stay in place without discomfort. The cup’s diameter and length also play a crucial role in fit, ensuring it sits correctly within the vaginal canal without causing irritation or protruding. Furthermore, features like an easy-to-grip stem or a removal loop can significantly enhance the user experience, making insertion and removal less daunting for those new to menstrual cups or seeking added convenience.

Detailed reviews
Flex Cup Slim Fit
The Flex Cup Slim Fit is specifically engineered for those with a medium flow, providing a reliable and comfortable experience. Its 22ml capacity is perfectly suited for managing moderate bleeding, allowing for extended wear times without frequent emptying. The cup features a unique pull-tab removal system, which makes removal significantly easier and less messy compared to traditional cups.

Users appreciate its smooth finish and flexible rim, which contribute to a secure seal and prevent leaks. This cup is an excellent option for individuals seeking a dependable and user-friendly menstrual cup for their medium flow.
Flex Cup Full Fit
While the Flex Cup Full Fit is designed for heavier flows with its 30ml capacity, it can also be an excellent choice for individuals with a medium flow who prefer longer wear times or have days with slightly heavier bleeding. This cup shares the innovative pull-tab removal system with the Slim Fit, ensuring a hassle-free experience. Made from medical-grade silicone, the Full Fit offers a slightly softer firmness compared to the Slim Fit, which can be more comfortable for some users. Its larger diameter and capacity provide extra security, reducing the need for frequent changes, even on medium flow days. The Full Fit is particularly beneficial for those who experience variations in their flow throughout their cycle or simply desire maximum protection and peace of mind. Its robust design ensures it stays securely in place, preventing leaks effectively.
Flex Reusable Disc
The Flex Reusable Disc, while not a traditional cup, offers a distinct alternative for managing medium flow, particularly for those seeking unique benefits. With a generous 60ml capacity, it provides extended wear time, often up to 12 hours, making it suitable for even the heaviest medium flow days. The disc’s design sits in the vaginal fornix, which can be more comfortable for some users and also allows for mess-free period sex. Made from soft, medical-grade silicone, it conforms to the body’s shape, creating a secure seal. Its rim is designed for easy insertion and removal, though it does not feature the pull-tab of the Flex Cup. The Flex Reusable Disc is an excellent option for individuals who prioritize comfort, extended wear, and the unique advantage of intimate activity during their period, all while effectively managing a medium flow.
Routine fit
Integrating a Flex Cup into your routine for a medium flow is straightforward and can significantly enhance your period experience. For most, the Flex Cup Slim Fit will be the ideal choice, offering sufficient capacity for 8-10 hours of wear, aligning perfectly with a typical workday or night’s sleep. Its easy removal loop simplifies the process, making it less intimidating for new users. If your medium flow tends to be on the heavier side, or if you prefer even longer wear times, the Flex Cup Full Fit provides extra capacity without compromising comfort. The key is to practice insertion and removal a few times to find what works best for your body. Many users find that emptying their cup in the morning and evening is sufficient, allowing for a more discreet and convenient period management routine compared to traditional products. The Flex Reusable Disc also offers a unique fit, sitting higher in the vaginal canal, which can be beneficial for those with a lower cervix or who prefer its specific design for comfort and other activities.

I’m pretty new to menstrual cups and the Flex Cup Slim Fit has been a good starting point. The capacity is just right for my medium flow, and I appreciate not having to change it constantly. The diameter of 40mm felt a little big at first, but I got used to it quickly. It’s definitely made my periods less stressful.
I was excited to try the Flex Cup Slim Fit because of the easy removal loop, but I found it a bit too firm for my comfort. While it definitely held up well for my medium flow and I didn’t have any leaks, I could feel it more than I’d like throughout the day. I might try the Full Fit next time to see if the medium-soft firmness is a better fit for me.
After years of tampons, switching to the Flex Cup Slim Fit was the best decision. The extended wear time of 8-10 hours is fantastic, especially on busy workdays. I love that I don’t have to think about my period all the time. It’s super comfortable and I haven’t had any issues with leaks, even with my medium flow.
I’ve been using the Flex Cup Slim Fit for a few cycles now and it’s been a game changer for my medium flow days. The 22ml capacity is perfect, I can easily go 8-10 hours without worrying about leaks, even overnight. The pull-tab removal system is seriously genius and makes it so much less messy than other cups I’ve tried. Highly recommend for anyone looking for an easier cup experience.
