Normally, a biochemical pregnancy bleeds for a week or less. A biochemical pregnancy is an uncomplicated pregnancy in which the fertilized egg does not successfully return to the uterus for implantation, but instead flows with the menstruation. The vaginal bleeding after a biochemical pregnancy is usually similar to a menstrual period. The amount of vaginal bleeding usually does not exceed the usual amount of menstruation and does not involve residual meconium, so the duration of vaginal bleeding does not exceed 1 week. If the vaginal bleeding does not stop, the patient should go to the Obstetrics and Gynecology Department for ultrasound to determine if there is any residue and undergo treatment under the guidance of a doctor. In addition, during the period of biochemical pregnancy, attention should be paid to keep the vulva clean and dry to prevent infection, avoid overexertion and cold, eat a light diet, maintain a calm state of mind, and consult a doctor if there is any discomfort.
