There are brown secretions on the tenth day of menstruation

If the menstrual cycle is normal, but the menstrual period is prolonged, up to 9 to 10 days, and the amount of bleeding is more, the menstrual cycle has ovulation, the luteal phase is well developed but the atrophy process is prolonged, resulting in irregular shedding of the endometrium. It is suggested to further check basal body temperature, coagulation function, blood routine, serum sex hormone determination, diagnostic curettage, endometrial biopsy and hysteroscopy if necessary to further clarify. Treatment should be given half cycle treatment after progesterone, chorionic gonadotropin or compound short-acting oral contraceptives to inhibit ovulation and control cycle.
