Vagina smell

Every vagina has its own smell. Right? My diet consists of water (regularly) , juice , fruits (as much as I can) and soda with junk food.🙄🙄. My discharge hasn’t changed or doesn’t have a smell so I know it’s not an STD , but my vagina usually has a smell when i wake up (I don’t sleep with any pants or underwear). Could it be sweat? Should I worry? My butt is big so could it be sweat from my butt lol😂? Idk. Am I the only one?
