If a gestational sac is present at 60 days of pregnancy but there is no fetal bud or heartbeat, this indicates that there may be a small gestational sac and embryonic abortion. Normally, the gestational bud and primitive cardiovascular pulsation can be detected by ultrasound examination around 45-50 days of pregnancy. In this case, it is necessary to determine the time of pregnancy in conjunction with the usual menstrual cycle and the time of menopause, and to perform dynamic observation. For women with irregular menstruation, the gestational week should be determined in combination with the blood HCG test, which may indicate that the actual development time is relatively short. For women with regular menstruation, if the fetal germ and fetal heartbeat have not appeared after more than 60 days of normal pregnancy, the possibility of embryonic abortion is generally considered to be higher, and they need to go to the hospital in time for treatment. Patients with embryonic abortion usually need to undergo an operation to terminate the pregnancy.
