You can't tell whether it's a girl or a boy judging by the heartbeat. My baby's was 162 and they thought girl and every appointment after it would fluctuate from 143 up into the 160s. I had a boy.

My boys and girl were all 150s

My baby girls heart beat was 150 the first time than the ultrasound was 160 and it's been the same since then

BOY

@beckiedickson19892009, not true for everyone my baby heartbeat stayed above 160 and it was a boy

Anything over 140 is a girl
