Women have their menstrual cycle every month, and it is important to pay attention to the condition. If any abnormalities are found in the menstrual cycle or volume, timely examination and treatment are necessary. Some female friends may experience premature menstruation, so they are very worried that it is an abnormal symptom. So, what is the reason why menstruation advances by one week every month?
A female friend's menstrual cycle advances by one week every month, which is likely due to physiological reasons. Every woman's menstrual cycle will have some differences, some longer and possibly shorter. So only when menstruation is regular and there are no other abnormal symptoms, menstruation is normal.
If a woman's menstrual cycle used to be around 30 days, but has now shortened by one week, it is considered an abnormal symptom, which may be caused by endocrine disorders such as irregular lifestyle, high stress, etc., which can affect menstruation. Moreover, women taking contraceptive drugs also have an impact on their menstrual cycle.
Nowadays, many women use contraceptive rings when using contraception. After placing the contraceptive ring, it may affect menstruation and cause women to experience premature menstruation, which is a common situation. Usually, it can return to normal after 3-5 menstrual cycles. In addition, women's ovarian function gradually declines from around the age of 40, which can easily lead to early menstruation.
