What Are The Side Effects Of Stress On Menstruation?

about 5 months ago, I moved to a different state. Shortly after, my period started being erratic. I was semi-regular and now it seems I have my period for almost a month, with only a short break in between. I'm not on birth control, and would rather not go on it. I have looked at a few things, and have seen that stress can affect your cycle and sometimes people just have crazy periods. Any suggestions?
