Nope with me didn't work..his heart rate was high like 160 and my hubby and I thought it was a gurl bc they have higher heart rates but we r having a boy and now his heart rate is 140
I am having a boy and the heart rate is 154 so it's not true.congratulations.

I was told that it is actually meant that during labor the girls heart rate is faster and the boys is slower. Not just any random time. But idk. My daughters were both anywhere from 130-160 at any given time
At about 5 weeks gestation, your baby's heart begins to beat. At this point, a normal fetal heart rate is about the same heart rate as the mother's: about 80-85 beats per minute (BPM). From this point, it will increase its rate about 3 beats per minute per day during that first month.
This is so exact, that your doctor or midwife can actually use heart rate to help pinpoint the gestational age of your baby via ultrasound. The miscarriage rate for pregnancies in which a mother has heard or seen a heart beat is less than 1%; however, if your doctor notices that your baby's heart beat is off by a week or more it can indicate that a miscarriage is more likely.
By the beginning of the 9th week of pregnancy, the normal fetal heart rate is an average of 175 BPM. At this point it begins a rapid deceleration to the normal fetal heart rate for the middle of the pregnancy of about 120-180 BPM. There is also a slowing of the normal fetal heart rate in the last ten weeks of pregnancy, though the normal fetal heart rate is still about twice the normal adult's resting heart rate.
They say the higher it is, the baby will be a girl if its lower it will be a boy.
my first ultrasound was 178, which it would mean girl. i am having a girl. but its just a old wise tale. as the baby gets bigger the heart rate will go down. or when their sleeping itll be lower.
