6 weeks 6 days low heart rate?

Li

I had my first ultrasound yesterday at 6 weeks 6 days and the doctor said everything was great and I was able to that heartbeat flicker on the screen 😍 The doctor said the heart rate was 119 and didn't seem concerned but that seems so low to me for almost 7 weeks. Did anyone's baby have a similar heartbeat around then and everything was okay?
