70 days of pregnancy with embryo bud but no fetal heartbeat

If a woman's menstrual cycle is regular, after pregnancy, the menstruation usually stops for about 5 weeks. The gestational sac can be seen by color Doppler ultrasound, and the fetal bud can be seen around 6 weeks. In the 7th week of pregnancy, a vaginal ultrasound can be done to see the fetal heartbeat. However, some women usually have a longer menstrual cycle. In the 7th week of pregnancy, if there is no fetal heartbeat, don't worry at this time, as it may be caused by late embryo implantation.

For example, patients with polycystic ovary syndrome usually have a long menstrual cycle, with less than one period in many months. It is possible that the embryo implants late, so only the embryo bud and fetal heart rate are seen, but not the fetal heartbeat. When encountering this kind of situation, we must first understand the patient's usual menstrual cycle. If the menstrual cycle is irregular, we can wait 1-2 weeks for a follow-up visit to see if there is a fetal heartbeat. If the pregnancy is more than 8 or 9 weeks, and there is still only the embryonic bud and no fetal heartbeat, it may be a sign of fetal arrest and you should have an abortion immediately or be hospitalized for medical abortion to terminate the pregnancy.

This situation may be a sign of fetal arrest. It is recommended to have a blood test to check the hCG value to see if the hCG value is normal, because the hCG value directly reflects the status of sperm and egg combination. It may also be that the pregnancy has not been long and the embryo has not been implanted for a long time, so there is no fetal heartbeat. At this time, regular prenatal check-ups are sufficient. Also remember to take folic acid tablets, eat more foods rich in vitamins and high-quality protein, and avoid fatigue caused by staying up late. If there is fetal growth retardation, it needs to be solved by medical abortion and uterine curettage.

The growth and development of the test tube embryo usually takes 30-40 days to form a gestational sac, 40-50 days to form a fetal bud and fetal heartbeat, and 50-60 days to form a fetal heartbeat. Therefore, a color Doppler ultrasound around 60 days will generally show a gestational sac, fetal bud and fetal heartbeat as well as a fetal bud and fetal heartbeat. Some female friends will have a color Doppler ultrasound before 50 days of pregnancy, which will only show a fetal bud and fetal heartbeat but no fetal heartbeat. This may be because the time is too short and the fetal heartbeat has not yet been formed. Therefore, you have to wait for a while, generally a week later, to see the fetal heartbeat. If there is still no fetal heartbeat after more than 60 days, first, considering that the embryo implants late, you can go for a follow-up visit. Second, it is recommended to do a blood progesterone test to rule out the possibility of test tube embryo termination.
