Patient's question:
NoDoctor's answer:
Hello, hello, endocrine factors, environmental factors, psychological factors, medication factors, and gynecological diseases, among other factors, can lead to menstrual disorders. Either early or delayed menstruation by one week is considered a normal phenomenon. If menstruation does not occur for more than 10 days or longer, a pregnancy test or blood HCG test can be used to confirm pregnancy. If pregnancy is ruled out, it should be considered menstrual irregularity and an endocrine examination is needed to identify the underlying cause.
