Special trashcans...? ?

How often do you think people clean the bins out? I'm use them and I'm afraid the girls next to me in the stalls in my high school can tell which pad is mine, bec our bins are shared by two stalls, you can open it from both sides. What do I do? All the popular girls stare at you after you get out of the stall and everyone knows your on your period. Idk what to do? I get really really heavy days and I'm afraid that girls will make fun of me.
