Is this normal?

I’ve been extremely stressed out lately and have had two panic attacks in the past week. I was supposed to start my period 4 days ago but it never came. I haven’t even been cramping, but I’ve had the usual symptoms of my period (back pain, headaches, craving sweets). There is no way that I could be pregnant unless I’m the next Virgin Mary 😂 Is it normal to skip your period or start late if you’re stressed?
