There is a small amount of bleeding a few days before menstruation

A few days before menstruation, there is a small amount of bleeding, which may be caused by hormonal changes in the body, such as taking emergency contraceptives and other estrogen and progesterone levels, resulting in withdrawal bleeding. In addition, attention should be paid to whether pregnant, there may be a small amount of bleeding. If the amount of bleeding is more considered, it may be caused by ectopic pregnancy rupture bleeding, which can be diagnosed by vaginal ultrasound. If there is a caesarean section or other uterine surgery, consider a small amount of bleeding that may be caused by the operation. In addition, it is recommended to pay attention to washing the local area with water every day during menstruation to prevent infection. If abnormal bleeding, it is necessary to seek medical examination in time.
