According to me, there's only advantages to not have to use tampons and pads. I convice all my female friends to try a menstraul cup cause it's simply the best!
It doesn't leak at night as pads do, it's cheap and environmentally friendly, but mainly that it doesn't dry out my mucus membranes and doesn't contain bleach and pesticides that I don't want anywhere near my uterus.
You are awesome and you have helped me to a better life. No need to carry around tampons, panty liners or to always bleed through because of useless tampons.
