How reliable is the heart rate/gender rule?

[bekki_d18]

Mine baby had a very quick heart beat but found out today i am having a boy, so not always reliable

I dont believe any of these methods, i think the only reliable way
is a gender scan from 16wks.

Euans heart rate was 150-160 through out and he sounded like a train... this time its the same so i say another boy.

my lil boy hb is always 140_160 nva lower then that so the theory dnt fit with me x

Whats between a babies legs has nothing to do with heart rate imo. Im surprised your MW suggested it was a girl because of this? x

Well,
I did IVF and at my 7 weeks scan, my doctor (amazing and world known) told me baby a would be a boy and baby b was a girl based on the hb. He was right, baby A is a boy. So, I guess it's always a 50/50 shot at being right.
