High heart rate?

I had my 34 week apt this morning and OB got baby’s HR at 165. She said they like to see it around 120-160 but because baby was moving and rolling the whole time she wasn’t worried and we just have a “happy” baby. But now I’m worried! Is that too high a HR?

I did have a bowl of cereal this morning and a yogurt drink so wondering if the sugar gave baby a high lol. I’ll be using my home doppler tonight to check on it again but could use words of reassurance.
