Menstrual cup and pool

MR

Hello!

I've been using the cup for a few years now and no problems what so ever, but I recently started working at the pool and I realized that everytime I get out of the pool I have to change my cup because it's filled with water 🤷🏻‍♀️

I swear the vaccum is established before I go into the pool, so I don't understand why this keeps happening...

Does anyone has the same problem or any advice?

Thank you 🫶🏻
