Help!

Can someone help me figure out how to read this ultrasound. I have a history of miscarriage. Of course the doctor could not see me but this was done by a tech. She wouldn’t say anything on how this looked. It will be 4 days before anyone will call to tell me if this is a viable pregnancy. I asked them to take blood work and they said no. Last time my doctor said to do blood work right away if I got pregnant again. I’m pretty upset. Any expert opinions out there? I’m worried that all I see is a sac.
