Doppler devastating for the fetus????

Zully
Last week I had my first prenatal care I was so excited to hear my baby's heartbeat I was 9 weeks and 5 days. The doctor did a quick ultrasound and showed me the heart. I asked the doctor can I hear my baby's heart? And she was like dopplers are devastating and I don't want to put the fetus on risk I was like okkkk!:/ never hear something like that.
