If you are 6 weeks and 5 days pregnant with buds and yolk sac but no fetal heart, the embryo may be developing normally but the fetal heart cannot be seen for the time being due to late implantation and small gestational sac, it is recommended to review the development in one week; or it may be due to embryonic sterilizations, which should be promptly aborted after diagnosis.
The gestation period is usually counted from the first day of the last menstrual period, and the embryo is usually shown in the 6th week of pregnancy, and the pulsation of the primitive heart tube is visible in the 6th to 7th week of pregnancy.
If there are fetal buds and yolk sacs but no fetal heart at 6 weeks and 5 days of pregnancy, it may be due to the late implantation of the fertilized egg, the gestational sac is still small and the fetal heart cannot be seen for the time being. It is recommended that the blood HCG level should be dynamically measured, and if all of them are within the normal range and there is no abnormalities such as abdominal pain, vaginal bleeding, and so on, it is recommended that the test be repeated in 7 to 10 days.
Failure to see the fetal heart, may also be caused by embryonic failure, normal pregnancy 6-8 weeks, blood HCG levels should be 66% growth rate, if the growth rate of 48 hours is less than 66%, the intrauterine gestational sac continued for more than 2 weeks without fetal heart, suggesting that the prognosis of pregnancy is poor, may be embryonic failure, if necessary, should be taken in time to comply with the doctor’s advice of artificial abortion.
During pregnancy, regular obstetric examination should be carried out, and if there is any abnormality, the patient should go to the hospital for consultation and symptomatic treatment in a timely manner.
