Missed period, normal?

I am marked as 8-9 days late. My menstrual cycles are always regular (28-35 days) , I have sex with condoms only + he pulls out even with the condom on every time . So I feel my chances of pregnancy are low, but you never know. I had my PMS symptoms a week before my scheduled period like normal the usual back pain, light cramping. I have not had any “pregnancy”symptom. Now I will say this is the most stressed I’ve been in a while. I’m a bridesmaid , between balancing family trips, funky work schedule , bachelorette weekend , and now the rehearsals and wedding coming up this week everything has been back to back. I feel a mess. So Idk if my period is delayed because of that? What’s the most you guys have been delayed during a stressful period? What should I do, I’m not mentally ready to take a test right before the wedding.
