Blighted ovum: What you describe is consistent with a blighted ovum. There will always be a yolk sac by the time a fetal pole is seen. There will usually be fetal heart motion seen by 6 weeks. To be sure, the ultrasound could be repeated in one week, but i would not be optimistic about the chance for a viable pregnancy.

Dates could be off: I would not expect to see definite fetal heart activity at 6wk 1dy. A repeat ultrasound in one week will resolve the question. If the pregnancy is viable there should be appropriate interval growth and definite fetal heart activity. If not, then there had been an early fetal demise. In cases of blighted ovum a fetal pole does not develop.
