- CGCaitlin G.5 hours agoRated 5 out of 5 starsI wore white pants on my second day
I love flex discs!!! I am someone who has a small pelvic floor and the cup is just too much for me. I have tried the discs and I am NEVER going back to tampons!!!! I can leave them in for a long period of time without worrying about leaking. They are so comfortable and reduce my cramping and bloating. I don’t even realize I’m on my period anymore. Serious life savers.
- JTJocelynn T.Verified Reviewer4 days agoRated 5 out of 5 starsI won’t be going back to tampons. Thank you :)
I first started using a period cup two years ago. I started on the small one and then I am 24 now two years later, I picked up a period disc from flex. I feel I love. I have recently just bought a period disc steamer to clean it and a disc portable cup cleaner. It’s the best invention since sliced bread. Thank you so much and I recommend to all my girl friends. 💗

I switched over to Flex about a year ago, and it has changed my life for the better! I don’t experience intense cramping anymore AND my periods are lighter. I’ve tried other disc brands, and Flex is top tier. I’ll never go back!
- ARAndrea R.1 week agoRated 5 out of 5 starsToo many good reviews, had to try myself
I've used this product the last four cycles, I can confidently claim this product is life changing! Sounded "too good to be true" at first, but I won't ever go back to pads or tampons, EVER. Pros: can't feel it, holds heavy flows, last for 12 hours, helped my symptoms (less cramping, length of period & overall feeling of being on my period at all).
Cons: can be different at first figuring out how to insert it correctly but the insert helps a ton! It does get messy when emptying, if it doesn't empty itself (I personally don't mind only dealing with it twice a day instead of pads & tampons so many times a day!!)
I have used it during sex and it wasn't messy at all, I was shocked.
I truly LOVE this product & always recommend it to others!

I’m 44 and went from pads to tampons and having almost allergic reactions. Almost always leaking or just feeling uncomfortable because I can feel the pad or tampon. Once I tried Flex disposable disc I was amazed. Didn’t feel weighed down and so easy to use! I would make one suggestion- maybe put a disposal bag with each disc?
