Levels look great.. Confusing US

So my levels look great.. 29,000 at 8w2d which is confusing the Dr about why there seemed to be an empty sac measuring 6w3d. I'm thinking the US tech missed something.. Has anyone seen something like this? Maybe baby is hiding? When I MCd in Feb everything shut down at 5w including my levels. This time they're right where they should be. Praying that my rainbow baby is just playing hide and seek or that it was a twin sac they just missed my little bean.
