Anomaly Scan Disappointing

I had my anomaly scan today I was so disappointed sa oby ko. She had many clients today because she will have her xmas leave. Wala pang 3-5 minutes natapos na kami. I was expecting detailed or atleast explanation about my baby. Kung tama ba ang laki or whatsoever. Nagsukat lang sya and print and layas na. Tama ba yun or ganun talaga ang procedure? I've heard kasi sa iba almost 30 minutes daw. Huhu.
