Vaginal dryness?

Im 20 years old, been on nuvaring for 2 years, but ive had this past year a lot of vaginal dryness, makes sex super painful and i dont carry lube with me cause the sex isnt often and such. Even if im reaaally turned on its nothing. Makes tampons painful to insert. Is there anything i can do? Natural remedies? Pill? Tips? Anything?!
