How often does your menstrual cup leak?

Je

So I'm walking home up a hill, suddenly I feel something not quite right. Like really bad. So I either just peed myself, or my menstrual cup is way over full. Now I'm just walking very slowly and carefully, congratulating myself for wearing black pants. 😅

I have to change my cup every two to four hours for the first four days of my flow. What is everyone else like?
