Is absence of fetal heartbeats during pregnancy a matter of worry?
Patient: actually i have done my first ultrasound of pregnancy in 6 weeks and 6 days for checking the heart beat of baby but doctor said no heartbeat has been formed. N ask me to come again after one week. So i just want to know the status n if there is something to worry? Doctor: Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice.  Actually in transabdominal ultrasound by 7 weeks fetal heart beat can be seen.  And in transvaginal ultrasound usually by around 6 completed weeks you can see the fetal Heartbeat. But sometimes when you are having wrong dates  you may not able to see the fetal Heartbeat according to your estimated gestational age. So,  better to wait for one more week as suggested by your radiologist and repeat the scan after one week if you are not able to make out the fetal heart even after one week the possibility of blighted ovum has to be ruled out.  Hope I have answered your query. Let me know if I can assist you further.
