When an empty gestational sac appears in early pregnancy, the HCG may double for a short period of time, but as the number of days of menopause increases and no fetal buds or fetal heartbeats appear in the empty gestational sac, the increase of HCG will slow down or even decrease. When a woman has an empty gestational sac after a dynamic HCG test and a gynecological ultrasound, the pregnancy should be terminated as soon as possible, as an empty gestational sac is not able to develop into a normal fetus. When a woman finds an empty gestational sac after pregnancy, most of them may be due to a decrease in the quality of the fertilized egg or the presence of chromosomal or genetic disorders, which may lead to natural elimination.
