I am leery of things like that. Cups didn't work for me at all. Why? I have a tipped uterus. Nowhere in the written instructions did it say that they can't be used if you have one. I had to watch the video to find that out. I hate watching videos.
I was having super heavy periods at the time. Thankfully I stayed home to try it out. And thankfully I had only a short nightshirt on and not pants. The cup retained fluid for about two hours. Then when I got up from where I was napping, all the blood gushed down my legs. I left a bloody trail all across the light colored carpet.
Then I played hell getting the cup out! It was stuck in there and did not want to budge. Thought I'd have to go to the ER. I exhausted myself trying. My hand and arm were totally covered in blood as was the toilet and floor around it. It was like a horror scene. Was never tempted to try anything even remotely similar after that.
Thing is, I didn't find out that I had a tipped uterus until I was pregnant. I'd had OB exams prior and nobody told me.
I had just read about these. I'm going to be a guinea pig and let you know. Since I'm working from home, if they turn out to be a disaster no one will be the wiser, haha. I ordered the Trial box of 24, which for me should be good for 4 or 5 periods because I will probably still use a tampon or pad overnight. I'm not signing up for the subscription. We'll see.
I like that they are disposable... and I also don't like that they are disposable. I didn't see anything about "recycling" or composting, which bothers me a little. Not that I'm into tree-hugging or anything but these are made with "medical" grade polymer, whatever that this. I bet it never decomposes, ever. But the idea of having to wash out the Cup was a big turn-off for me and I would have tried something like that if it was more user-friendly, like this one.
