Anyone had a late period after Pfizer vaccine?

I’m on the pill and Thursday November 10th, was my last active pill also I got my third vaccine shot the same day, I didn’t take the placebo hoping it will come without it

But today is November 16th, and I still didn’t get my period, do you think it’s from the vaccine?

Also I didn’t get sex in that month, only one time and we used the withdraw method
