high heart rate at 32 weeks?

Is 120 high for a pregnant woman? Last time I was at the dr's they were watching it but never told me if it was too high. 
I've been wearing my Fitbit (not sure how accurate this thing is but pretty close to the numbers I was having at the dr's) and even when I am laying down, doing nothing, it's at least 103-110. 
I've had the Fitbit since before pregnancy and before that, my normal heartbeat was about 80.
