Sometimes the environment causes physical stress too, not just mental/emotional stress. You’re in a new place with new food and water, new routines, etc. which can definitely mess with you a bit even if you don’t feel stressed out. It wouldn’t hurt to go see a doctor, but late periods happen with big life changes like that. Maybe tmi but several of my periods were either late or nonexistent during my first semester too, and it was all stress related
