Menstrual disorders: It is common to see patients who come to the clinic with irregular menstruation, and each time they ask for a medical history, they are unable to make sense of their bleeding for a long time. Women’s menstruation is cyclical, including menstrual period, late menstrual period, luteal phase and premenstrual period. When regulating menstruation, you need to use medication according to different menstrual cycles and symptoms, so your description of the bleeding time and amount is especially important. We suggest you to think about your age of menarche (the age of your first menstruation), the time between each period, the interval between periods, how long you have had irregular periods, whether there are any triggering factors such as tiredness, staying up late, business trips, intercourse, emotional changes, etc., whether there is any change in the volume of menstruation, the time of menstruation, any dysmenorrhea, and whether there are clots in menstrual blood.
