Stress is the main culprit of a late period. The Hypothalamus of the brain is responsible for regulating your period.

During stress, the brain stimulates the pituitary gland which secretes hormones that prepare body for fight or flight. These hormones also suppress various functions of the body including the reproductive system.

If you are under a stress for a long time, then your body stays in flight or fight mode, which stops ovulation temporarily. This stoppage of ovulation delays your period.   

Stress dramatically affects women’s menstrual cycle. Stress will either prolong or shorter your period or cause missed period.

To come out of stress, involved in daily activities, do regular exercise, and sleep well. These activities will distress you and maintain your regular menstrual cycle.

If a woman experiences chronic stress, she should talk to a doctor, who can help her.

The same mechanism of action is applied to implant patches and injections.

The action of hormonal therapy is continued for up to 3 months. When you stop birth control pills you will get a regular menstrual cycle again after three months.
