The term “great aunt” generally refers to a woman’s menstrual period. It may be normal for menstruation to occur a week earlier, or it may be caused by endocrine disorders, pre-miscarriage, fibroids, etc. Normal menstruation is cyclical and self-limited. The first day of bleeding is the beginning of the menstrual cycle, and the interval between the first day of two menstrual periods is called a menstrual cycle, which usually lasts for 21 to 35 days, with an average of 28 days, so it may be normal for menstruation to be one week early. One week early menstruation may also be caused by recent changes in lifestyle, such as irregular diet, lack of sleep, mental stress, etc., which may lead to endocrine disorders, resulting in disruption of estrogen and progesterone secretion, which in turn may cause menstruation to occur early. Early menstruation may also be caused by pathological factors, such as pre-miscarriage with low bleeding which may be mistaken for menstruation; or early menstruation may be due to uterine fibroids and other reasons. There may also be other reasons for early menstruation, so it is recommended that you consult a doctor in a timely manner, complete the relevant examinations, clarify the cause of the disease under the guidance of a specialized doctor, and target the treatment.
