Stress stops periods: Stress can stop periods by sending a message to the part of the brain above the pituitary called the hypothalamus. This can occur with the death of a loved one, serious physical illness, anorexia,or stress related work issues. Make sure that you always use contraception, check for negative pregnancy tests every month and start resolving stress issues by stress reduction techniques like exercise.
