Empty Baby

My ultrasound estimated that I am 7 weeks pregnant, you can see the baby with a heartbeat and an empty sac??

I’m not for sure what I should be thinking, you can see the heartbeat and baby just fine, and then later we found an empty-looking yolk sac, what does this mean?

Nothing. You’re fine, baby is fine.
Sometimes the cell splits early and there is an empty sac. Sometimes you drop 2 eggs and only 1 is fertilized, there are lots of explanations, including the sac being the placenta forming early and getting ready to sustain baby.
One egg was fertilized and you have a healthy baby implanted in the uterine wall, congratulations!
