Doctor's answer:
Hello, early or delayed menstruation by one week is a normal phenomenon. Of course, if you have had sexual activity, you should first check whether there is a possibility of pregnancy. You can use a pregnancy test kit one week after the delay to confirm. If the menstruation is delayed, it is also necessary to consider factors such as fatigue, poor rest, stress, anxiety, environmental changes, gynecological inflammation, and endocrine disorders, all of which can lead to delayed menstruation. It is recommended to go to the hospital for tests including the six sex hormones and ultrasound to identify the cause and then receive targeted treatment.
