SAVED MY LIFE FROM THE ENDOMETRIOSIS SUPER HEAVEY FLOW
I have used tampons plus backup pads for most of my life due to my super heavy flow and horrible debilitating periods plus endometriosis. When I first discovered Flex discs I was skeptical that it would be any better than what I was used to. I WAS WRONG! These things are a game changer: I can swim, I can work long shifts, I can do whatever I want while wearing one and the only thing that happens when my flow is at its heaviest is a bit of auto-dumping when I go to the bathroom. If the disc becomes too full, the seal is broken by the force of the pelvic muscles during urination. However, when that happens all I have to do is (with clean hands) push it back into place. They have given me back my freedom. Also, I have never given birth (as is recommended before you use certain kinds or sizes menstrual cups) and these are very easy for me to insert.
Unfortunately, using flex discs did not lessen the severity of my cramps, but that was not the reason I switched to them and I wasn’t too disappointed because I know my cramps and period pain are extremely severe. So that wasn't a dealbreaker.
A word of advise: if you have to poop, wash your hands before going to the toilet and remove the disc FIRST, empty your bowels, wash your hands again THOROUGHLY, and then insert a new disc. In my personal experience, it’s very difficult to insert the disc when you are about to poop because there’s less space in the vagina when the rectum is full.
The only people I wouldn’t recommend these…

10/10 love
I got the disposable ones because I wasn’t sure about a reuseable flex disc and these are great, weird to insert at first but once you get used to it it’s a life changer. My cramps have been nonexistent and my periods are actually shorter! It’s great to not have a tampon string or have to worry about smell. I will say if you don’t change after 12 hours or if you have very heavy flow there is a risk of leakage but it depends on each person, I only had leaks the first period I tried this

Absolute Game Changer
I first tried them 2023. I used Cups before but wanted to try Discs for the longest. I hate Tampons and Pads. Flex was a Game Changer for me. Currently we are in Germany and I even have them shipped here since they are not available on Base or in any local Drugstore. So worth it. My Period was usually super heavy and long. Now since using the Discs and Period Panties my Flow isn’t as heavy and long anymore. It took some Practice to get them sit comfortably but once you figure it out it’s smooth sailing.

Every period go to (for myself at least.)
Okay, so when I first discovered these I wasn't sure. I did so much research lol. The first time it hurt, not terribly just like a stretch typa hurt. But it was only the first 3 times (I genuinely think I was doing something wrong lol) but after figuring out what the easiest way to use for me was it's been smooth sailing. I have the reusable disks as well. I have heavy periods and generally I don't have to wear a liner while wearing the flex disk (sometimes leaks occur but like I said I am a heavy bleeder).
I could keep going about how this is an amazing product. Highly recommend. Super convenient and clean.
