Stress bleeding

Does anyone else bleed or have a bloody discharge when stressed? I should be ovulating right now (my regular period was over a week ago) but I am bleeding pretty heavily right now. I am also stressed. I always have regular normal periods but have bled like this twice before...once during my divorce and once right before I got remarried. now I'm stressed about something else. I'm 99.9% sure I'm not pregnant but I'm wondering at what point should I be worried or call my Dr?
