Can stress do a number when you get your period?

Cathrine
This month has been one of the craziest of my life. I've been so stressed I've not been sleeping, barely eating and as a result I am nauseous cause my body doesn't want to eat like I used to and when I got my period it was crazy heavy. The cramps weren't unbearable but the bleeding was. I am on my second day so bleeding normally is heavy but never usually THIS heavy. Could this be because of stress??
