Could This Be Twins? One With Yolk Sac and One Without?

1 baby or 2?

One baby with heartbeat in the left hand corner of the sac. The other thing the tech said was a yolk sac, but it looks as if there is a baby attached to that yolk sac too? I haven't seen a doctor yet and that ultrasound was only done for a free study so the tech said she couldn't tell me anything. I thought that the yolk sac was suppose to be attached to the baby not off floating on it's own? Thanks Mommies : )
