Gestational sac measuring smaller

I did a frozen embryo transfer of a day 5 blastocyst and during my first scan at week 6 day 4, my gestational sac measured smaller at week 5 day 3. There was also no yolk sac and heartbeat visible. My understanding is that the dates would be very accurate for ivf, and measuring behind on my scan made me very worried. Does this mean the pregnancy is not viable? Any positive stories of similar situation that anyone could share?

You’re right - you should be able to see a heartbeat at this stage, and with IVF, your dates indeed would be pretty accurate. This happened to me before and my doctor asked me to scan again at week 7 and week 8 but still there was no heartbeat, so it was a miscarriage for me. Your doctor probably would ask you to come back and scan at least one more time - my doctor said in some rare situations, it still worked out. Good luck!!!

thanks for sharing and for the well wishes! Really hoping that a miracle would happen when I return for a scan next week...
