My Period is late

Harper

I'm 14 and I've had my period for half a year now. It almost always comes on a normal basis, the day it's predicted to come.

This cycle I've had really bad PMS (bloating, depression, mood swings, and nausea) and my period is a few days late.

I'm not sexually active, but I'm nervous that something's wrong. Am I just paranoid??? Is it normal for a cycle that's usually normal to be irregular?
