6wks, spotting a week, elongated sac not round on us, looked full of blood (no yolk visible) fetal pole no heartbeat but right size. any chance?

Possibly: Do you know the actual measurements ?There is a guideline that can be used called the 5-10-20 Rule for Crown Rump Lengths and Gestational Sacs > if  you have 5mm CRL you should see heart beat, this should be by/at 6 weeks >if you have 10mm GS, you should see a yolk sac, if not then nonviable >if you have 20mm GS, you should see a fetal pole, if not then nonviable. Again these just guidelines.

Ominous: The findings of a deformed gestational sac with internal echos and no heart beat is ominous. However, tests are not perfect. I suggest you have the test repeated in one to two weeks.
