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
When I saw my doc at 16 weeks my daughter's was 149 so 160 sounds perfectly fine as well.
What normal for 17weeks mine was 160 on Monday when I went. I went have my next appt until I'm 21 weeks
Yes that sounds normal :) congrats!
