Was true for me I'm having a girl!

Nope all my kids had high heart rates

I studied the theory in depth and found that it’s only true during labor for a yet to be explained reason. People told me from ten weeks our first heartbeat to our reveal that it was a boy. I ignored all of them and knew since 9 weeks, before I heard the heartbeat or saw the US that it was a girl. My mother’s intuition was right.

Boys were in 145-155, girls 165.

Mine has been in the 120's and it's a girl

Thanks everybody, this gives me hope it could still be a boy! We have a girl and she was in the 140s and this one we are really hoping for a boy since we may not get another chance at getting pregnant.

My daughter was consistently in the 150s and it's been the same now with this pregnancy (a boy)

My son stayed at 150-170 until 28 weeks then he dropped down

Crap. None of my boys were ever 140. Always 150-180

It was right for me but it’s just an old wives tale!

Not true! I’ve had above 140 every time with this baby, usually around 150, and I’m having a boy!

No both my boys were 150-160

I find them very incorrect son's was high daughter's was low

Was not correct for my older 3 or my current pregnancy lol
