Irregular menstruation, menstruation does not go late, but very little menstrual volume

There are many factors that can lead to irregular menstruation, such as diet, environment, endocrine, mood, etc. Menstruation is prolonged but menstrual volume is rarely considered to be caused by endocrine disorders, which may be caused by lack of estrogen antagonism in the body, which leads to continuous shedding of endometrium stimulated by estrogen. It is recommended that the patient see a gynecologist, take blood for sex hormones, clarify the cause, and symptomatic treatment.
