Switching to a menstrual disc can feel like a big change, but the Flex Plant+ Disc makes the transition easier than ever. Designed with plant-based materials, this disc offers a comfortable, leak-free period experience while being kinder to the planet. Whether you're new to discs or just need a refresher, this guide will walk you through everything you need to know.

From understanding how the disc works to mastering insertion and removal, we've got you covered. By the end of this article, you'll feel confident using your Flex Plant+ Disc and wonder why you didn't switch sooner.
What is the Flex Plant+ Disc?
The Flex Plant+ Disc is a plant-based menstrual disc that sits lower in the vaginal canal, resting behind the pubic bone. Unlike tampons, which absorb blood, discs collect it, allowing for up to 12 hours of protection without the risk of Toxic Shock Syndrome (TSS). The disc is made from a flexible, plant-based polymer that molds to your body for a custom fit.
One of the standout features of the Flex Plant+ Disc is its design. The rim is firm enough to stay in place, yet flexible enough to be comfortable. Plus, it's disposable, making it a hygienic and convenient option for those who prefer not to deal with cleaning reusable products. For a more sustainable option, you might also consider the Flex Reusable Disc, which offers the same comfort with a longer lifespan.

- Holds up to 3 times more than a super tampon
- Can be worn for up to 12 hours
- Mess-free and leak-free once inserted correctly
- Made from plant-based materials
Step-by-Step Insertion Guide
Inserting the Flex Plant+ Disc is easy once you get the hang of it. Start by washing your hands thoroughly. Then, squeeze the disc between your thumb and middle finger, pressing the sides together so it forms a narrow oval. This is the key to a smooth insertion.
Next, find a comfortable position—squatting, sitting on the toilet, or standing with one leg elevated works best. Gently insert the disc into your vaginal opening, aiming it toward your lower back (not straight up). Push it in until you feel it settle behind your pubic bone. You should not feel it once it's in place. If you do, it might not be far enough back.
- Relax your muscles to make insertion easier
- Use a water-based lubricant if needed
- Practice makes perfect—don't get discouraged if it takes a few tries
How to Remove the Flex Plant+ Disc
Removal is just as simple. Again, wash your hands and find a comfortable position. Insert your index finger into the vagina and hook it under the rim of the disc. Gently pull it down and out, keeping it upright to avoid spills. The disc's design allows for mess-free removal, but you can also do it over the toilet if you're worried.
After removal, wrap the disc in its original packaging or a tissue and dispose of it in the trash. Do not flush it. If you're using the Flex Reusable Disc, you can rinse and reinsert it after washing with mild soap and water.
- Don't panic if you can't feel the disc—it's likely in the right place
- Bear down with your pelvic muscles to help bring the disc within reach
- Always wash your hands before and after removal
Common Mistakes and Troubleshooting
One of the most common mistakes is not pushing the disc far enough back. If you can feel it, it's probably too low. Try inserting it at a downward angle and pushing it gently but firmly. Another common issue is leakage, which usually means the disc isn't positioned correctly or is too full. Empty it more frequently if needed.
If you're experiencing discomfort, the disc might be too large or not inserted correctly. The Flex Plant+ Disc is designed to be comfortable, but everyone's body is different. If it doesn't work for you, consider trying the Flex Disc, which has a slightly different shape, or the Flex Ultra Thin Pads as a backup option.
- Use your finger to check that the disc is behind your pubic bone
- If you feel pressure, adjust the angle of insertion
- Don't wear the disc for more than 12 hours
Tips for Beginners
When you first start using a menstrual disc, it's normal to feel a bit awkward. Give yourself time to practice, especially during lighter flow days. You might also want to wear a panty liner as a backup until you're confident in your insertion skills.
Remember, the Flex Plant+ Disc is designed to be mess-free and comfortable. Once you get the hang of it, you'll enjoy the freedom of not having to change your period product every few hours. For those who want to save money and reduce waste, the Flex Disc Annual Supply offers a year's worth of discs at a discounted price.
- Start with a small amount of lubricant
- Try different positions to find what works for you
- Give yourself at least two cycles to get comfortable
