I have PCOS and have only had a period once every year or so for most of my life unless I used hormone treatment. I'm now 38 and have had a monthly period for the last 9 months. I know part of my problem was that I wasn't used to having a period, but it's also the only time I experience gender dysphoria. I feel my body isn't mine when I'm on my period and having to change products regularly. Then came the flex disc! I originally intended to use a cup but got a size that was too large, so I tried the disposable disc that came with the cup. WORLD CHANGER! My cramps were reduced, I didn't have as much mess, it wasn't as uncomfortable, I could insert and remove easily on light days, and not worrying about my product for 12 hours helped the dysphoria more than I can say! I'm only giving it four stars because it was a little too firm for my liking, but switching to the reusable disc fixed that issue perfectly.
