Yes, that's perfectly fine. Also, if somebody asks you: - Шта има ново? (what's new) you could answer: - Нема ништа ново - there is nothing new or ништа ново - nothing new here you could also add: "Све по старом" (literally it means: "Everything is in an old way" but if we translate it normally, it means: "Everything is the same") I hope I helped you. If you need any help, feel free to ask me. Good night.
