My oldest heart beat was always in 160s my second was 190s and this one has always been 170s they are all boys. I don't think there's really a difference
At all of my appointments, from 10 weeks til now (22 weeks) my sons heartbeat has been in the 150's every time.
They say a higher heartbeat a girl, I thought..
My doctor says its not but I see all my girls heartbeat was high
