What should I do when I haven't been given any updates on my work schedule?

For context I work at a store where only 1 person opens and 1 person closes, my old boss would always text me the work schedule to know when Im working but he transferred to another store and I have a new boss who I havent met yet, This is the second week now I havent been given updates about my work schedule, last time I asked my coworker and he said neither of us were on it for the week, so I dont think I can ask him again because he wont know. So what should I do because the new week starts tomorrow? Would my new boss have my number on record and text me? Should I assume Im also not working this week?
