My babies HR was up and down - I have a son.
My babys HB has always been between 130-145bpm and it's 100% a BOY!
Im having a girl and her heartrate has been in the 150s and now its in to 130s to 140s. So it just depends.
Heartrates are usually a little higher then the 120-160's at about 10-14 weeks. After that they go down. Like Kim said it has nothing to do with the sex but rather to do with what you are doing, eating, drinking, or if the baby is sleeping, kicking, jumping. Like a normal adult a babys heartrate goes up and down. I listened to my daughters every day and at 10 weeks it was usually around 170 then a couple weeks later it fluctuated from 136-160, sometimes within seconds.
HR for every ultrasound has been in the mid 160's and I'm having a girl!
Mine was ranging from 160-180 and it's a boy.
HR has always been 150-160 and we are having a boy...
there is no connection between heartrate and sex. the babys heartrate is influenced by many things. what you drink, eat, how you feel....etc.
my sons heartrate was 170 for the longest time.
I posted this question a while back lol. Its not true.
It is just a wives tale.. Someone posted something similar to this about a month back, and there was TONS of feedback. I think it was pretty much unanimous that is is NOT accurate! Good luck!
My little girl's HR this afternoon ( I had an ultrasound) it was 141bpm. So maybe you'll be having a boy....Good luck .. Let us know
