Do I have to remove the menstrual cup when I go to the toilet?
No. You can normally go to the toilet when you’re wearing your Lunette. After a bowel movement, you might want to check that the menstrual cup is still sitting properly. Please do not forget your hand hygiene here!
So does your blood just sit there?
Technically yes, but you don’t have to worry about leakage. Unless you like, absolutely forgot you had the cup inside you because it’s just that comfortable. Your blood might overflow and only then would leakage be a problem.
