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!
Thanks to you it doesn't even matter any more which week I booked my vacation!
I have only used it during one period so far and I'm sold! Don't need to think about it, so nice to go and do what one wants and to not constantly have to think about if you have tampons with you etc... I love my cup!
