Embryo non-attachment usually does not have obvious symptoms. Failure of embryo implantation means that the fertilized egg does not successfully localize, adhere and penetrate in the uterus, indicating that conception has failed. Under normal circumstances, there are no obvious symptoms, only that a woman’s menstruation will come on time every month, and there will not be any menopause, and it is not possible to ascertain whether or not the embryo has implanted by the individual’s physical manifestations. Clinically, if you want to know whether the embryo is implanted or not, you still need to use professional examination and tools, through the early pregnancy test paper or HCG test to see the hormone changes in the body, such as HCG has continued to grow and increase several times, it suggests that the embryo is successfully implanted, and some of the patients may be accompanied by slight bleeding, abdominal pain and other conditions.
