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!
A small revolution is what the menstrual cup is. No purchases, no smell. Freedom to just be for a whole day, no waste, always available, no chafing, no itching. Simply the best!
Congratulations on your 3 year anniversary! I recently started using a menstrual cup and the only thing that I'm sad about is that I didn't start with this sooner. It's amazingly great in every way!
