It is possible to have a pregnancy reaction in the absence of a fetal heartbeat. Pregnancy reaction is mainly related to the elevated HCG value in the blood, which is possible whenever there is a fertilized egg implantation and there is a rise in HCG. Fetal buds and primitive heart tube pulsation are usually visible around 7 weeks of pregnancy, while pregnancy reaction usually appears around 6 weeks of menopause, and it is also possible to have a pregnancy reaction before the appearance of fetal heart and buds, and in a small number of patients with embryonic arrest, there can be a sudden disappearance or alleviation of the pregnancy reaction. In early pregnancy, there may be no obvious symptoms, or there may be vaginal bleeding and loss of pregnancy reaction, but it is difficult to detect through symptoms. Diagnosis can be made by ultrasound, and any abnormalities should be seen in the obstetrics clinic.
