I am not sure either but ages ago one of the girls in my earlier due date group, she had an older MW who told her that if the babies hb sounded like a horse galloping then it would be a girl, if it sounds like a train chugging then its a boy. I think it only works later in the pregnancy though.

Nikita had a hb of 150something at 6 weeks, this little beanie had a 154 bpm hb at 8 weeks - who knows - Dh is convinced its a girl.
