Such a rude person‼️‼️‼️

Extremely upset with how the sonogram came out, very blurry compared to the the last ultrasound. The tech was extremely rude and in such a hurry, I only got to hear the heartbeat for about three seconds, she has terrible bedside manner, I complained to the doctor and am going to write a letter to the manager. On a sidenote I am nine weeks today the baby's heart rate was 168. Due October 28th. Heart rate was 144 when I went in two weeks ago. Any guess on gender?
