We've heard women with a tilted uterus say that FLEX disc is the only menstrual product they've used that fits their shape, while others say it does not fit at all. So there's no clear-cut answer: it really depends on your individual body.
FLEX works by creating a seal around the cervix to catch the menses. As long as you're able to position FLEX around the cervix and create a seal, it should work. Just know that this might take some time and exploration to get right.
Our Flexperts are here for you, though! Shoot us an e-mail to firstname.lastname@example.org with any questions.
