How high was your baby's heart rate?

I've had 24/7 nausea since around 5 weeks. At the ultrasound at 7w6d heart rate was 161 and on doppler at 12w2d it was 170.

The nurse that read me the ultrasound report asked how I was feeling and when I told her how sick I was she was like "well, the heart rate is 161 so the baby is

.. busy."

This got me thinking about how people often say higher heart rate means a girl and more nausea means a girl. I'm having a boy so that's obviously not the case, but interested if heart rate and sickness are correlated.
