I've been using a menstrual cup for about 18 months now, and it is one of the best decisions I ever made.
I've always had heavy periods (I think it's partly genetic, partly being young, and partly pcos), so pads and/or tampons had to be changed frequently, and as a chronically ill and disabled person that was not always easy or possible, so there was often some leakage. I also had trouble with skin irritation with pads, and the risk of toxic shock syndrome with tampons made me anxious. So, for almost a decade I found periods incredibly stressful and uncomfortable.
Then, a couple of years ago, I came across some YouTube videos about menstrual cups. I was intrigued, they are reusable and last for years so cause far less waste, they can hold much more than the largest pads and tampons so there is far less chance of leaking, and with them being worn internally there wasn't the worry of skin irritation like with pads, and the risk of tss is pretty much nonexistent so that stress minimised, and long term you save a huge amount of mony.
It took me 6 months to finally commit to buying one to try it, it took a couple of cycles to fully become accustomed to using a menstrual cup, but I am do glad I stuck with it. It changed my life
There have been a couple of times that I have had to use pads and tampons because I started my period unexpectedly early and was spending a couple of nights away from home so had to grab what the nearest store was selling, and it felt like hell to go back.
Now that I use a menstrual cup my periods are about as stress free as it is possible for them to be. I highly recommend that you try one.
