Gender prediction via ovulation!

Sy

I apologize if this question has been asked already, but I'm curious on more input. I have read other forums that stated they could tell sex if baby by which side they ovulated on. First instance if you ovulated from the left it means you're having a girl, and if right, It's a boy. Now I do know sperm is supposed to be the only thing to determine gender, but I'm still curious to see if there's any truth to this?
