Heart rate

Lindsay • After 9 miscarriages,we got our little miracle in Feb 2016. My little Aidan! Trying now for baby #2!
What is your baby's heartbeat around 16-17 weeks? Last week at my doc it was 146. I was at the hospital yesterday and it was 132. Does this seem low? My Doppler usually shows around 160 before, making me worried 😕
