Life saver
Incredible. I tried a cup once and it was a nightmare. It scared me off for a long time. I decided to try the disposable discs after a moment of reconsideration and it was fantastic. It went so well I bought the reusable one and it's my first cycle with it, I'm sold. I have severe cramps, and I have noticed a massive difference with these. I still get them, particularly bad on day one, but when I used tamps I would cramp full time all week. With these, I almost didn't have any. I felt day one, and the rest of the time it was a rare ache here and there. Some days nothing at all. I love that I can sleep with them. I barely leaked overnight on my heaviest day (I normally do with tamps, even the extra supers, and I have to set alarms to change them because even with overnight pads I've had mishaps). I only needed a panty liner for that one night! One thing though, I could auto dump with the disposable option. I also had a few leaks with the disposables, on my heaviest day. With this reusable option, I cannot seem to auto dump. It's said that's because with the size and composition it's a better fit for my body. That's fine, I can deal with that. But it's a little disappointing because I enjoyed the auto dump spring my heaviest days when I didn't want to need longer breaks at work or on the go to handle that. I have decided to use disposables during that time instead so I could utilize that, but the rest of my period the reusable is great. Now about placement. I am in my late 30s, one delivery by c section. I watched multiple videos online and was nervous about getting it right and getting it out. I found it totally easy to get it in and tucked my first try. It was totally comfortable, didn't feel it at all. The disposable ones tend to slip on me while using the restroom and need to be readjusted, but this reusable one doesn't do that. Removing it was a bit of a learning curve. The disposable ones were easier to remove for me, the thinner lining and more pronounced edge made quick work of hooking my finger under it and pulling it out. This one's more flush and rounded and the material made it a little more difficult to do that. I had a mess my first attempt, and I was glad I tried that at home where the sink is nearby and I had plenty of clean up options. The second time, I tried to move more slowly and get the feel for it, but it fell in the toilet. I never had that happen with the disposable ones and it was pretty annoying and gross. I was not at home for that situation, it was a public restroom, so I just had to let that one go. Thankfully I bought multiples, which I HIGHLY suggest for just that situation. But after that I have seemed to have figured it out and no longer having any difficulty with it.

BEST for postpartum mamas!
Okay, so I was skeptical. I have been using a diva cup for about a decade. I recently had a baby and all of a sudden diva cups weren’t working for me anymore. Even the postpartum ones would sink down during the day, leaked, and ultimately were uncomfortable. I was VERY unsure about the disc and felt clumsy inserting it and didn’t trust the self emptying feature. In full transparency, the first day I used it, I didn’t get it to sit properly and it collapsed during a yoga class and when I tell you I BOLTED out of that class haha. Since then, I have put it in and pushed it up against my pubic bone and then ROTATED it. That does the trick. And then even if you self empty, make sure to kinda put it back in place. After I got the hang of it, it has very few leaks, is more comfortable than a diva cup, is easier to empty, holds more, and is easier to insert. For all postpartum mamas, this is the way. And for the diva cup nay sayers, don’t knock it till you try it.

Revolutionary! But may be too large for some bodies
I'm writing this after my first cycle using the Flex Disc. I've never used any kind of menstrual cup or disc before, and I've been converted! I chose to try a disc as opposed to a cup because I get cramps, and tampons tend to make them worse, so I figured I'd be better off trying something that sits in a different location. I was also intrigued by the auto-emptying feature. Inserting the disc was surprisingly easy. It went into the right place on the first try. It was almost a little anti-climactic -- I had expected to struggle with it. But nope! I think I had mildly worse cramps on day 1, compared to just using pads, but nothing I couldn't handle. The reward was SO worth it! Instead of feeling wet and gross all day and worrying about leakage, I was dry and carefree! I did a couple of pretty intense workouts (boxing/kickboxing, squats, and abs) and didn't have any problems at all. I take showers in the morning and at night, and I cleaned and re-inserted the disc during those times. So basically, I only had to deal with having a period twice a day. It was amazing. I had very minor leakage on my heaviest day, and when the auto-emptying feature works, it causes some leakage too. Think about it -- if some blood is dumped out, there will naturally be some left in the canal after you wipe, and gravity will bring it down eventually. So I still wore a pad each day. Moving forward, I'm going to look into getting some period underwear to pair with the disc, so that I can completely dump the pads and be more eco-friendly. In terms of comfort, I am very sensitive. I used to have an IUD, and if I put my mind to it, I could feel the IUD up there. This was the same way. It didn't hurt to have the disc in, and it wasn't uncomfortable per se, but if I thought about it, I could feel it. That being said, I forgot about it the majority of the time when I was at work, at the gym, etc., so it certainly wasn't bothersome. I just don't know if the description "if it's in correctly, you won't feel it" is totally accurate for more sensitive folks. Anyway, I 100% recommend this product. It's so worth it to be less tied to regular period products, and to basically be able to forget about having a period outside of twice-daily cleaning and re-insertion. The disc made my period experience so much better that I want to tell every menstruating person I know! UPDATE, 2.5 years later: After reading more about menstrual discs, I've learned that when a menstrual disc constantly auto-empties and needs to be pushed back into place most times you use the bathroom, it's probably a sign that it's too big for your body. That was definitely my experience with the Flex. It auto-dumped a lot, and I felt the need to check that it went back to the correct spot every time that happened. Often it didn't and needed to be pushed back into place. My Flex disc developed a crack after 2.5 years, which meant it was time for a replacement, so I tried a disc that is just a little smaller in diameter (Cora Perfect Fit). The Cora PF auto-empties less often and typically goes back into place automatically. I am very grateful to the Flex disc for introducing me to a better menstrual experience, but for some bodies, like mine, a smaller disc is just a better fit.

Life changing
My only complaint is that I’ve been watching their ads for years and they didn’t convince me to switch sooner. Life changing protection, comfort, and ease. If you’re scared to switch— don’t be. It’s worth it for the price of one period’s worth of tampons for a device that works better and will last YEARS. My only advice for a newbie is to try it on your days home to get a hang of it. I realized quickly that sneezing makes me self empty lol. But once I knew that I could bear down and prevent any leaking. But again… just do it.

Flex Menstrual Cup Review – A Solid Upgrade with a Few Learning Curves
Flex Menstrual Cup Review – A Solid Upgrade with a Few Learning Curves I’ve been using the Flex menstrual cup for a few cycles now, and while it’s not my “Goldilocks” disk, it’s definitely a big improvement over what I was using before. I previously used the Saalt Small Cup, and while it’s a popular option, it just didn’t work for me. The suction on that cup caused pretty uncomfortable cramping, it was tough to get it to open properly, and I found myself having to empty it multiple times a day—only for it to still leak, even on lighter flow days. Enter the Flex cup. It took a little practice to get the hang of insertion, but once I got used to the technique, it went in pretty smoothly. The design is definitely more comfortable for me than the Saalt, and I love that I only need to empty it every 12 hours thanks to its larger capacity. That’s been a total game changer for busy days. Removal is still a bit messy, but not overwhelmingly so. It’s manageable, and I think with more experience it’ll get even easier. It’s not the most perfect fit (still on the hunt for my ideal disk), but it does its job well—no cramps, no constant leaks, and far fewer bathroom trips. Overall, I’ll definitely keep using it. It’s a solid, reliable product that works way better for my body than the cup I was using before.

Best period product I've tried so far! Pays for itself
I recently found out I have fibroids. I bleed heavy and go through the biggest tampon in about an hour. This gives me much more time to not worry. Every couple of hours I go to the restroom to auto dump it, so if you push and kegel a couple times, it will empty all the way without having to take it out. I previously tried cups which I could feel and they were harder to get into position since I have a low lying cervix as well. They barely fit my body and are much messier than discs, especially when out in public because you have to remove them. (These also hold more) The auto dump is amazing but make sure it's notched back into place after doing so. While you don't have to take it out for your cycle at all, I usually remove, wash with gentle fem soap and reinsert daily while in the shower. Removal and insertion is easy to me now. I don't get any irritation from it. No reduction in cramps but I'm sure that's my fibroids fault. I'm glad that I've switched! I will never look back. I think the best part is no worry of tss, no having to remove it, not feeling it and how much it holds. My only qualm was when I first got it, I was so paranoid that I wasn't using it properly and that it would leak even when I had it in right. Being used to 20 plus years of tampons Def had me on a learning curve with these. I can't blame the flex for that. Just took a little bit for me to get used to using. I do have leaks on occasion still due to severe, heavy bleeding but it's always on my heaviest day while I'm sleeping for extended periods. I've had much less incidents after switching and HIGHLY RECOMMEND.

REAL REVIEW
Alright ladies, let’s talk about the flax disc. 1.does it actually work? -yes! I used it for the entirety of my last period and experienced no problems or leaking 2. Is it comfortable? -yes! Once in place it feels exactly like a tampon (or doesn’t feel because you literally can’t feel it once it’s in) 3. Is it convenient?-maybe, it’s convenient in the way that you don’t have to worry about running out of tampons or pads, convenient that you only have to check it 2x a day (for me, may need more for a heavier flow) and convenient that you can sleep with it in and not have to worry. NOT convenient because yes, let’s be honest, it can be messy to take out to empty, plus it can be messy putting it back in since there is no applicator to put I in for you. It’s not convenient because if you are in a public restroom and don’t have a cleaning container (buy the pixie cup one, it’s amazing and breaks down for storage) it’s near impossible to clean your disc. 4. Is it long lasting? -yes! It can last for years if cleaned properly and not damaged by boiling (get cleaning solution and water or buy a cup/disc steamer to protect the disc from burning) eventually like everything else it will need to be replaced, however it comes no where close to disposing 14 tampons or more, a week every month. 5. Does it actually help with cramps?-yes! I typically cramp ALOT on my period, my last period with the disc, I did experience some cramping, however it was no where near as much cramping as I would have with tampons 6. Can you actually empty it without taking it out?-yes and no. Because the flex disc only comes in one size, if you’re not a heavy bleeder (like myself usually) you won’t have a lot to empty. This being said, it will be harder to empty a little bit without taking it out, then emptying the majority if you were a heavy bleeder. Also be cautious that in order to self empty, you have a high chance of it coming out of place and needing to be readjusted. My personal opinion? Just take it out to empty and re-insert, a lot easier and guaranteed you won’t leak after. TO SELF EMPTY- you’re going to want to be sitting on the toilet and push as if you were trying to go #2. Your muscles essentially will push the disc down to empty. Finally, #7. Is it better than cheaper discs?-yes! I have also tried other brands and no other discs compares to the flex disc. The flex is made with high quality medical grade silicone, while others tend to have a more plasticy feel to them and bend less easily than the flex disc OVERALL - an amazing product and I highly recommend it. It’s eco friendly and not linked to TSS which was a main seller for me. However, u do wish the company would make different sizes to meet the needs of different flows. Having a larger disc with light bleeding seems excessive instead of just using a smaller size.

FLEX IS THE BEST :):):)
Quick update /protip: When inserting, for best seal, sometimes, esp durring heavy flow, i pat my lower canal down so its not inserted into a super wet mess. This was my only original issue and i figured out if o did a little rinse or pat pat, the disc sealed perfectly never with any issue. Original review: Frankly, I LOVE THIS DISC. Only seriously motivated to review it after deciding to venture out when my last/first flex disc was ready for retirement. This time, instead, I bought the pixie cups. I figured I'd get both since, why not, and I'd never tried the upper sized ones so was curious and got the two pack. The smaller pixie was too small, to soft, it bubbled up creating no bowl to catch. I liked the string/easy removal idea also but it's just not comfortable like the flex. The flex is amazing. Litterally, it would be best if I set an alarm because it's SO COMFORTABLE, I feel nothing so if not for cramps or a teeeeeeeny bit of red that can come when wiping for pee, or for poo the cup self empties some so it's a good reminder, oh I have period protection to take care of 😆. Flex is a dream. I tried allllll of the cups. They don't feel good, i can feel them, the ends /bottom part/tips press on your soft exit area when sitting, and moving, or just with no movement at all. Im returning / processing refund for the pixies. The small needs to be bigger and more ridged and the large, well im 36 and have not had babies but wow SO SO SO FIRM. I feel the standard flex is the best of both these worlds fitting right in the middle and would likely be good for both pre and post birth women. I traveled the world with mine for two years. Let me say THESE ITEMS SHOULD ONLY BE SOLD IN CLEAR!!!!! PINK AND PURPLE, NON OPAQUE COLORS ARE DANGEROUS!!! The clear allows you to see what and where is not clean and needs to be cleaned. Mine easily lasted two years. And no I could not boil as often as needed giving my living circumstances but, probably due to its clear color, I could clean very well anything left behind. ALL of the other ones I used besides the... idk the name maybe also flex is hot pink with honey comb texture on the bowl area, gained weird smell I could never get rid of. My personal ph is likely better now but regardless this thing NEVER EVER smelled weird and I am one of those "super smellers" who can smell strongly things that other people can't even pick up. Love this disc. Worth every penny. Will stay with them. My yoni is really not happy with pixie. I feel if you like that one you haven't tried this one. I get removal is "harder" with no string, but relaxing and bearing down was always plenty to retrieve and you sacrifice completely comfort for a 1 second challenge of removal. Love flex. Thanks yall ✨️✨️✨️
