Period is later than usual-could stress be a factor?

Hey guys so my period is a week late and I’m not pregnant, I’ve had all the normal symptoms that I usually do while on my period, such as craving sweets(that only happens during my period). I’ve been pretty damn stressed because my boyfriend is moving away and I was just starting to become attached, so yes I’m feeling depressed, angry, and stressed. I’m even more stressed that my period hasnt came yet because that just messes with my hormones.
