Old wives tale.

140s-150s boy
160s-170s girl

If you believe the old wives tales then your boys would actually be girls. Because in the "old wives tales" if a baby's heart rate is under 150 it's a boy and over 150 is a girl... So I would say the wives tales are obviously false.

I'm a nurse and believe my OB. I didn't say that are connected but he's a believer of wives tales as so am i

Heart rate and gender are not related. Im sorry your ob made you feel like they are but there is absolutely so connection.

The baby's Heart rate doesn't stay the same... it fluctuates with whatever the baby is doing in the womb. It lowers when the baby is sleeping, and increases when the baby is moving about. A baby's heartbeat doesn't determine gender at all.

@courtneyraelochamy My Ob Swared with my two previous with the heart rates both 153 boys and he was right and now it's 168 with my third.

Heart rate has nothing to do with gender. Old wives tell lol

I say boy
