I'm late😱😕

So I'm 11 days late and I'm not sure what to do, I'm freaking out. I'm trying not to because I know that would make it worse. I was very out of it last week (emotional/stressed).Last month I was late by 5 days.  I've been getting PMS symptoms, except one of the usual (sore breasts). Any advice?
Update: found out last night, I'm pregnant.
