Yes that sounds normal :) congrats!
What normal for 17weeks mine was 160 on Monday when I went. I went have my next appt until I'm 21 weeks
When I saw my doc at 16 weeks my daughter's was 149 so 160 sounds perfectly fine as well.
At 12 weeks my babies heartbeats were 164bpm and now I'm 24 weeks and it was 143bpm and my midwife said that was perfect
