How do I solve my late period caused by stress?

I was due on my period a weeks ago, but still haven't got it. I am usually fairly regular, but I am in the middle of my exams, could it be stress related? I highly doubt that I am pregnant, I have only had sex once and it was safe (all precautions taken) and it was after I was due on so that can't be what's delayed it.
Is there anyway I can restart my period? How long will this last? Will it cause any health issues?
