Flex cup (menstrual cup)

Tried the flex cup . I’ve never used a tampon ever so it took me quite some time to figure out how to put it in and stuff but I absolutely love It it . I work from home right now so It was easy to clean in between dumping them and stuff but what about when I’m now at home and it’s time to dump? I can’t just walk out from a public bathroom go to the skink and rinse it 😂 I’m so confused on what I should do when I have to dump in public bathrooms .
