Is it weird that I don't get PMS or PMT when I have my period?

When I have my period I'm completely calm and happy. The only time I get angry or stressed (when I have my period) is when someone says or does something annoying or offensive. I don't get angry at little things, I'm just as happy as I am when I don't have my period. The only time I get emotional is when I have cramps but I keep that to myself. Is this normal?
