The appearance of brown discharge during non-menstrual periods may indicate the imminent onset of menstruation and approaching menstruation in the case of adolescent women. Moreover, some adolescent women, due to irregular living status, may also have endocrine disorders and menstrual disorders, thus leading to brown discharge. Don’t worry too much, you can adjust your daily life, pay attention to rest, avoid straining, keep a relaxed and happy mood, and take endocrine regulating drugs if necessary. If the bleeding is not discharged in time, the color will change from red to brown for a long time. It is recommended to have a gynecological examination and ultrasound if necessary, because some diseases can cause brown discharge, such as vaginitis, cervical polyps, cervicitis, and cancer of the cervix.
