The flex disc is amazing!!! I get 3-week-long, heavyish periods due to my birth control, so I go through a lot of pads. I’m so glad I invested in this because now my waste is reduced, I can leave it in for 12 hours without worrying about toxic shock, it’s super comfortable, and I love the auto-dumping because I don’t need to manually empty it. Easy to insert, just took me a couple practice runs. It can be a little messy when removing but it’s so worth it.
