Usually, embryo biochemical bleeding occurs. Embryo biochemistry, or biochemical pregnancy, is a condition in which the fertilized egg does not successfully implant in the uterus and miscarriage occurs. In this case, the patient’s estrogen and chorionic gonadotropin decrease and the meconium naturally peels off, causing the patient to bleed. The amount of bleeding caused by this condition is usually slightly more than the usual amount of menstruation and is accompanied by pain in the lower abdomen. Since the symptoms of embryo biochemistry are similar to those of menstrual flow, patients need to distinguish carefully. If embryo biochemistry is suspected, patients should seek medical attention promptly to clarify the diagnosis and determine the progress of the condition through ultrasonography, routine blood tests, serum HCG and other relevant tests. Since this embryo has not entered the uterine cavity, treatment such as clearing surgery or curettage is not required. After embryo biochemistry, patients should strengthen vulva care, wash promptly after each urination and defecation, and maintain good hygiene habits to prevent infection. Develop reasonable living habits, ensure sufficient sleep and avoid overworking. It is advisable to have a light diet and you can eat more nutritious food, such as lean meat, chicken and eggs, to promote physical recovery.
