Hi, I had my first ultrasound at 6wks pregnant and we found a gestational sac and yolk sac at 5wks 4days. Just this morning (now 8wks 2days)we had a transvaginal ultrasound to check for fetal pole and heartbeat . Sadly, we did not detect any fetal pole and heartbeat but only gestational sac and yolk sac. The ultrasounds read 6wks and 2days. I am worried since this is an ivf cycle and the dates are accurately counted by my gyne. My dr said to do another ultrasound next week. I m worried. We had ChatDoctor blood test done and it was 27,000. Do I need to worry about my pregnancy not being viable? Pls help....
I am sorry, but this pregnancy is very unlikely to be viable.  At Chat Doctor level of 27000 a fetal pole with active heart beat should be seen.  With 2 weeks of passage of time, one would also expect normal progression of structures seen on ultrasound, from sac and yolk sac at 6 weeks to sac with fetal pole and heartbeat at 8 weeks.  Generally a repeat ultrasound is ordered to assure parents that the diagnosis is correct, only because it is emotionally so difficult.  Good luck.
