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?

What I know usually for week 5 to 7 it is pretty hard to see the yolk sac and heartbeat. Most of the time on the next check then it can be seen and hear the heartbeat. I did not take IVF but this is also for normal pregnancy. I did scanning on my earlier weeks and it is like a peanut/bean size. Doctor did explain to me. Perhaps you can wait for your next appt.
