Could my pill be getting too hot?

So im on sprintec and i take it every single day never missed a pill and always on time! When I go to work, I put my pill in a plastic bag and put it in my wristlet and keep it in there all day until its time for me to take my pill ( my wristlet only has a few cards in it & a travel size feminine wipe)... Could this cause my birth control to become ineffective or am i overthinking it? I carry my wristlet with me all day so im just wondering if it could make my pills overheat, they dont feel hot but im just a little bit concerned.
