Disc vs cup: TMI things to know from a long time user!
By Grace Rowe on Reviewed in the United States on May 25, 2023
First off, I’ve been using both cups and menstrual discs for years. They. Are. The. Best. I bought light “period underwear” for small leaks which I only have to use on my heaviest days. More on that later. Both cups and discs are cramp-free. Read that again. No more cramps. I don’t know the magic but if cramps ruin your life this information might just save it. Totally worth the learning curve! You also shouldn’t feel them while you are wearing them. If you do, you should try a different one, since not all discs/cups are created equal! I started my journey with another brand of discs which I could feel and leaked frequently. This one is the best one I’ve personally tried, but know if you’re built differently then perhaps this one might be problematic for you, while another brand works perfectly. Don’t be afraid to experiment. For heavy bleeders: discs are great for those first couple of days or so. They self-empty when you go to the bathroom, which means you don’t have to ever switch out period products ever again in public bathrooms. Truly, you only need take it out at the end of the day and replace it with a new one! Easy peasy. Beginner friendly since they are disposable. No washing or sterilizing like the cup requires. I know that really grosses out some people. Just toss it. Downside is, you will have to buy them monthly just like most other period products. Not so with the cup (there are discs designed to be reused as well but I do not personally have experience with them, and this review is about this disposable one anyway). Let’s talk disc leakage. It should be minor, unless it gets dislodged during a restroom break. This is my biggest frustration with discs. Sometimes it’s good, but it’s recommended to check its placement after using the bathroom since it sometimes gets out of its place. If you don’t catch it, then it won’t do it’s job. Since they are designed to empty out you may find they might leak with, say, a badly timed sneeze or cough even if it’s in properly. Even so, a light back up pad is normally all you need in such circumstances unless it was very full to begin with. If you feel a leak starting, head to the bathroom. Most of the time that means it is overfull. A light liner is usually all you need for these leaks if caught right away. To sum up: discs are not totally leak-free, but that is actually what makes them so amazing for heavy bleeders, since they freely “leak” into the toilet. Unfortunately they can shift during that process so it’s not totally set-and-forget it, either. Oh wait. Period sex? There is DEFINITELY a learning curve with this. Not so much leak-wise (though I wouldn’t try it if it’s full), but the guy can feel it. Keep that in mind and start slow. There was a BIG difference in this area between this brand and the other one I have tried. This one wasn’t as “sharp”, although hubby is still not a fan so I’m not sure I can recommend it. Cups! Cups are virtually leak-free in every sense with the proper fit. They are not nearly as “one-size-fits-all”: shorter, taller, wider, skinnier, firmer, and softer versions means you may have to try multiple brands and styles before you find one that’s perfect for you. With a proper fit, you should not be able to feel it. They do not self-empty, which means you have to take them out, dump them, and reinsert if they get full. However, in my experience by day 2 or 3 you can easily go all day without having to dump it. I’m a heavy bleeder. If you are a light bleeder, you should be able to use the cup from day 1 for a leak-free period. Outside of the initial “cavity blood” making its way out (the stuff that was already there before you put the cup in - quite minor), you could honestly go without a liner and be good all day as long as your bleeding isn’t heavy enough to fill it up. After day 2 or 3, I normally do this myself. I wear regular underwear and not even a liner for back up. That’s how leak-free it is. With a cup, there should be no sign of your period until you dump it out at the end of the day. No cramps, no blood. 5 stars. You do have to wash it, so “dealing with it” is messier in that sense, maybe. They say to boil it on a stove to sterilize it between cycles, but I find throwing it in the dishwasher works great (it’s only after I’ve already washed it, but if that freaks you out then do what makes you comfortable). I recommend owning at least two cups to let them “breathe” between uses: I don’t personally use the same one non-stop for 7 days even with proper washing habits if I can avoid it. To sum up: I hand down prefer cups over discs on lighter days, because I can completely forget about it all day. No “reminders” when I go use the bathroom. On heavy days, I sometime do a cup, sometimes I do discs. A disc and light liner is easy to keep in your car or purse if you’re caught off-guard while you’re out. That’s it! Hope this has been helpful. Always happy to share TMI if I think it will help out. Try these discs out, you will love them!

Save your money if you have a heavy flow
By Karen B on Reviewed in the United States on May 15, 2025
Although I agree these are comfortable to wear, and I appreciate they are not tampons and the health benefits of using the flex disc is better than tampons, I did not have a good experience, and I was really hoping to. I do have heavier periods for a day or 2 sometimes, and I knew that the disc was more likely to leak then, but that heavy day, I was having to go to the bathroom every hour or so to let the flex disc empty, because it started leaking, which is as bad as a single super tampon for me on those days. That night, the disc leaked really bad before I woke up, and thankfully I was wearing a pad too, just in case. Resetting and changing the disk, especially if you’re bleeding heavy is messy, and I don’t know how it can’t be. I personally haven’t experienced even 8 hours of no leakage, except during my super light flow, as my period is finishing up. I was really hoping this would work as an alternative to tampons, but I unfortunately find tampons more effective and less messy overall, and still had to double up with the disc and a pad, not panty liner, because the leakage was so much. I gave this 3 stars, only because I’m sure it might work for someone with a consistent light flow
