Heart rate 10 weeks - too low?

Hey help please..

I just had a scan I’m measuring 10 weeks 3 days and the heart rate was 118

The nurse said it was a healthy baby and we watched it move and flip around on the screen

I was concerned the HR was low and asked and she said it was all perfectly normal and it was a “strong heart beat” and the healthy range is 110-170

I’m abit of a paranoid worrier and I read a lot on the internet and I still feel this is very low!

I’ve had three precious scans and all was perfect and at 6 weeks the baby heart rate was 158

Has any one else had hr near 118 at 10 weeks? Was all ok?

Thank you - from a self confessed worried messss!
