What does this mean

Cortney

I’m 22+2 with a girl and I had my anatomy scan and my ob had to rush to the OR so I missed the appointment with her to talk about it but she emailed me saying that my baby looked normal but she is measuring small and they are sending me to a high risk doctor to remeasure her and make sure she’s okay but I’m scared I don’t know what could be wrong or if she’s okay
