The main reason for taking birth control pills during the college entrance exam is to postpone menstruation, because many patients experience menstrual cramps or heavy periods, which can affect their performance during the college entrance exam, so many people use birth control pills or progestins to postpone menstruation. The specific method of use is usually to start taking the pill about 1 week or 10 days before your period, and take it once a day for the entire delayed period. However, the pill has certain side effects, and some patients may experience clinical symptoms such as dripping vaginal bleeding or dizziness and discomfort during the use of the pill, which can be left untreated if the symptoms are mild, but should not be stopped blindly if the symptoms are severe. If patients blindly discontinue the medication, they will soon have menstrual flow, which will disrupt women’s endocrine secretion and lead to menstrual disorders.
