Any ultrasound tech who can help me with my baby’s measurements?

See the attached image, did I measure the BPD right? I think the tech might have measured my baby wrong and thus small for his age. I am grasping at the last straws here. She was wrong with the gender too and they had a new machine to use which she was learning. So I am thinking baby measuring small due to this vs something being wrong? Pls NO negative comments or passive aggressive statements. I am worried and need a bit if help.
