Why is my period always 10 days early?

Menstruation always 10 days early is considered to be related to heredity, endocrine dysfunction and so on.
1. Heredity: If a woman’s menstruation is always 10 days early since the first menstruation, this situation is considered to be related to heredity, and then it is considered to be a normal phenomenon.
2. Endocrine dysfunction:
(1) Mental stress: If the patient’s recent work or study stress is relatively high, it will easily lead to endocrine disorders, which will affect the normal ovulation function of the ovaries, and then menstrual disorders such as shortened menstrual cycle and abnormal menstrual flow will occur.
(2) Gynecological endocrine diseases: If a woman has polycystic ovary syndrome, luteal gland dysfunction and other diseases, due to irregular ovulation of the ovaries or premature atrophy of the corpus luteum, which will lead to menstrual disorders such as early menstruation.
For women whose menstruation is always 10 days early, it is recommended that they go to the gynecology department of a regular hospital to improve ultrasound, sex hormones and other related examinations, and then take active treatment under the guidance of the doctor after clarifying the cause of the disease.
