Second opinion ultrasound?

K • Pregnant with #1! Each day is a blessing
I had gone to the doctor for my first ultrasound yesterday at around 9 1/2 weeks. They sent me to the tech who then did the abdominal and transvaginal ultrasounds. She took a total of 15-20 minutes then says to me here is the yolk and the baby but there is no heartbeat and you're only measuring at 8 weeks 1 day. She was silent up until that time and I was wondering if anyone else has had something similar happen and gone for a second opinion?
