“Auntie” refers to menstruation. When menstruation is delayed, it is necessary to consult a doctor for a blood or urine test, ultrasound, etc., to determine whether or not you are pregnant. For those who suspect pregnancy, the first thing to do is to clarify the time of the last menstrual period, the menstrual cycle, and whether there are any recent symptoms or discomfort. Then a blood or urine test for human chorionic gonadotropin, or HCG, will be performed to determine whether there is a change in its value and whether it meets the criteria for pregnancy; ultrasound will also be performed to determine whether there are signs of early pregnancy. However, delayed menstruation does not necessarily mean that you are pregnant, but can also be caused by taking hormone-containing medications, surgery resulting in adhesions in the uterine cavity or cervix, obesity, excessive dieting, polycystic ovary syndrome, premature ovarian failure, chronic hepatitis, tumors, severe anemia, and excessive mental stress. Therefore, it is recommended to consult a doctor to find out the cause of delayed menstruation after it has been delayed for at least 7 days longer than the normal cycle. For delayed menstruation due to pregnancy, HCG test and ultrasound can clarify the cause.
