Failure to see fetal heartbeat at 9 weeks of pregnancy basically indicates fetal arrest, and if necessary, prompt medical attention can be sought to terminate the pregnancy.
Generally, the gestational sac and the primordial heart tube can be seen on ultrasound as early as the 6th week of pregnancy. If no fetal heartbeat is seen at 9 weeks of pregnancy, the gestational sac may be underdeveloped, and the pregnant woman may repeat the ultrasound three days after the examination to rule out a misdiagnosis. If there is never any change in the gestational sac, it means that fetal arrest has occurred, and timely medical attention can be sought to consider termination of pregnancy.
Fetal arrest may be related to maternal endocrine hormone level disorders, chromosomal abnormalities, poor embryonic development, abnormal living environment, etc. Pregnant women should undergo a systematic examination after fetal arrest to clarify the cause of fetal arrest and prepare for the next conception.
It is recommended to pay attention to rest in life, ensure adequate sleep, avoid strenuous exercise or stay up late for a long time, etc., should also maintain a happy mood, pay attention to monitoring their own changes, and if there is any abnormality, seek medical attention in a timely manner.
