Freaking out but I shouldn't be

So I had my ultrasound done to find out the gender of my baby.  My doctor sent me a msg saying overall the ultrasound looked good but there were some parts that she was unable to see bc of the size of the baby and position, to schld back in two weeks for another ultrasound to keep an eye on the baby..I'm freaking out! I know she said everything is fine but I can't help but go a little crazy. I already sent her a msg but she's taking her sweet time replying. Then I see this in the ultrasound report and I don't even understand crap. Does anyone know what it means?
