Is it harmful to take medicine to delay menstruation?

Under normal circumstances, menstruation comes once a month, but there are always some special situations in life. For example, some students have physical tests for the high school entrance examination. If they happen to have their periods on those days, they must find ways to postpone it, because physical reasons will affect the test results. They can take medicine to postpone it, but this is very harmful to the body. Taking medicine will slow down the secretion of hormones and cause system disorders. So what are the other harms? Let me introduce them below.

Drugs that delay menstruation are generally sex hormone drugs, which themselves may cause endocrine disorders and affect the normal menstrual cycle. So if it is not necessary, it is best not to use it. But if there are special circumstances and you need to postpone your period, you can only take medication, but the frequency must not be too many.

It is recommended to eat spicy food or drink excessively, and then do more intense exercise. If you are married, you can have sex after that, which usually works. Take progesterone, or go to the hospital for progesterone injection, and it will come soon.

I've tried drinking black fungus and white sugar water. Eating chocolate may work, I used to delay it that way - if you want to delay it, you can eat olives before your period, but don't eat this after your period, otherwise you will eat a lot or take progesterone, and your period will come after you stop taking it. You can also drink more herbal tea!
