Missing a period can be an alarming experience. If you have already ruled out pregnancy, your mind might start racing through a list of medical worries. However, one of the most common reasons for getting a change in the cycle is not a disease at all but it is stress.
The human body is highly sensitive. When the brain might sense that you are under pressure, it can just "pause" the reproductive system. Below, we shall explain the science behind a stress delayed period and how to tell when it is actually the time to see a doctor.
The Science: Why Your Brain "Pauses" Your Cycle
Your menstrual cycle is controlled by a delicate conversation between the brain and your ovaries. The main "command center" is a tiny part of the brain which is called as the hypothalamus.
As per the medical research, the hypothalamus is highly responsible for releasing the hormones that shall start period. But there is a catch: the hypothalamus is also the part of the brain which manages stress response.
When you are very stressed, the body shall enter "survival mode." This decides that it is not a safe or healthy time to potentially carry a pregnancy. To further save energy, the brain shall simply stops sending the signals needed for ovulation. If you do not ovulate, the period will not arrive on time.
The Culprit: Meet the Stress Hormones
When you face a difficult situation, the body releases stress hormones, primarily cortisol. This hormone is great for helping in reacting to immediate danger, but long-term stress can lead to cortisol levels to stay high.

- Hormone Imbalance: High cortisol can simply lower those levels of estrogen and progesterone in the body.
- Delayed Ovulation: If the cortisol shall spike right before you are supposed to release an egg, the body shall simply delay ovulation by days or even weeks.
- Late Period Stress: It can create a frustrating cycle. You are well stressed, so the period is late. Then, you get stressed as the period is late than it keeps the cortisol high and delays it even further!
