“Old wives' tale 2: Fetal heart rate predicts the baby's sex
According to this rule – it's been around for 30 years, so I class it as an old wives' tale – if your fetus's heart rate is above 140 beats per minute (bpm) you're expecting a girl, and if it's below you're expecting a boy.”
Is this true? I did my last scan at 12w 3d and baby’s heart rate was 167bpm.
