25 days after blastocyst transfer, HCG 60,000 without fetal heart and fetal buds may be normal. 25 days after the transfer, HCG value is normal, may be because the pregnancy time is still less than six weeks, the embryo is still in the process of development, can not see the fetal heart and fetal buds, you can consider a week later to go to the hospital to recheck. The embryo’s development speed is different, so the time for the fetal heart buds to appear is different, but the latest should not be more than 60 days. If the pregnancy is more than 60 days to check, there is still no fetal heart, fetal buds, consider fetal arrest or empty sac is more likely. In this case, do not be nervous, one week later to check again, if there is still no fetal heart and buds, may be the transplantation failure.
