Biochemical pregnancy HCG value usually does not exceed 1000IU/L, which is at a low level. Biochemical pregnancy is an abnormal pregnancy phenomenon in which the fertilized egg fails to properly implant in the uterine cavity and is expelled from the uterine cavity, and the HCG value in the blood changes from rising to falling due to the end of the pregnancy, which causes the endometrial lining of the uterus to slough off, and vaginal bleeding occurs. Under normal circumstances, when a woman is about 5 weeks pregnant, the value of HCG in the blood does not exceed 1000 IU/L. When the pregnancy ends due to a biochemical pregnancy, the value of HCG in the blood decreases significantly until it reaches the level of the gestational period. Biochemical pregnancy is the fertilized egg did not normal implantation, does not cause too much trauma to the body, most do not need special treatment, in the biochemical pregnancy end of the next cycle of physiology can still continue to prepare for pregnancy.
