Doctor's answer:
Generally, at 8 weeks of pregnancy, primitive cardiac tube and fetal bud can be observed. The size of the embryo is between 1.5-6.5cm, with an average of about 3.23cm. Based on your test results, there is no primitive cardiac tube and fetal bud, and the possibility of embryonic developmental delay or fetal demise cannot be ruled out. Since some women may have late implantation of the fertilized egg or slower embryonic development, the above situation may also occur.
