It would be the exhaustion stage of stress model ( developed by Selye).
Explanation:
Hans Selye was a famous medical researcher as well as endocrinologist.He has given theory about a stress model which is based on psycho biology as well as physiology as General Adaptation model.His model explains that an event which threaten a person's well being leads to a three stage bodily response.These three stages are: alarm, resistance & exhaustion.
ALARM STAGE: Its is recognised by flight or fight response in reaction to any stressful situation. The body adapts in such a way that it reacts very quickly in wither the confrontation or fleeing the threat posed to them.
RESISTANCE STAGE: In this stage the parasympathetic branch of the ANS counteracts the changes which stress has produced an attempts are made for the restoration of homeostasis.There will be increased glucose in the blood, high BP but stress hormone levels begin to return to normal which enables the body focus to shift from alertness to renovation.
EXHAUSTION STAGE: The body don't have any energy left to cope with the continued stress in the long term and when it continue the body will show the signs of exhaustion. There will be gradual deterioration if it persists.
Menstruation is the process in which the uterus sheds blood and tissue through the vagina. This is natural and healthy in girls and women of reproductive age. Western communities call this a period.
