missing period, due to stress?

Hi everyone. So, I have been on the pill for three years, never had any mess ups or anything. This month my boyfriend and I have only had sex 4-5 times and we use the pill + him pulling out. Usually on my period week my period comes on Tuesday morning, but it’s Tuesday afternoon and it hasn’t came yet. I have had normal cramping and such but no blood.

But, this weekend I witnessed my great grandmother literally, literally, hurt my dog, have a real psychotic break (very long story very scary) and I had to drive home in the middle of the night two hours away. I was EXTREMELY stressed and have had extreme stress and anxiety since then... do you think stress like this could be delaying my period?

thank you

edit: i do not feel as if i am pregnant at all and that’s not a giant concern, I just want to know if you think this stress could be delaying it.
