A missed aunt (period) is not necessarily pregnancy, but can also be irregular menstruation. For women of childbearing age who have regular periods and have normal sex, the first thing to consider after a delayed period is whether or not you are pregnant, which can be tested with an early pregnancy test. If pregnancy is ruled out, not having a period is one of the symptoms of irregular menstruation. It may be related to endocrine disorders, taking medications, environmental changes and so on. If your period does not come for more than 10 days, it is recommended that you can use the test paper to test yourself, and if it still shows that you are not pregnant, it is recommended that you seek medical advice. Occasional delayed menstruation is usually not a big problem, but if the menstrual irregularities for a long time need to be taken seriously, it is recommended to follow the doctor’s instructions to do the relevant tests to clarify the diagnosis and timely treatment.
