Women's menstruation is normal within a week of their original cycle, so when the patient's menstruation is two days ahead of schedule, it is normal simply from the menstrual cycle. However, if the patient shows less vaginal bleeding, consider the following possibilities: First, the patient has just come to menstruation, endometrial exfoliation is less, so the amount of bleeding is relatively small, generally the second-third day of menstruation will increase, so the patient can continue to observe. Second, consider that the patient is pregnant, is threatened abortion or ectopic pregnancy, so show a small amount of bleeding. In this case, the patient needs to check the blood chorionic gonadotropin, progesterone for differential diagnosis. Third, consider menstrual disorders, such as endocrine disease or endometrial damage, resulting in reduced menstrual volume, this situation needs to do gynecological ultrasound, endocrine examination or hysteroscopy, differential diagnosis.
