I did. Said I was having a boy, and I have a daughter. It's purely an old wives tales and shouldn't be taken as an absolute.
its like a flip of the coin, either way it is going to be right or wrong as there are only two options. sadly nothing works other than an ultrasound as it has the highest chance of being correct
I did for all 5 and it was right 4x and wrong once;)
It was wrong for both of mine.
So far it's been right for me with both of my boys, it says I'm having another boy, so we will see if it was right again. haha I think it's just fun, there is no way it can be accurate.
