Mamas who pump at work! Haaaaalp! Lol

Okay this might be a dumb question, when i pump at work into a storage bag.. can i just let it stay out till i get home to refrigerate it? I plan on pumping about halfway through my shift and then nursing lil man when i get home. I just don’t have the ideal refrigerator situation and figured if i could I’d make it as easy as possible on myself.
