Old wives tale

So have you heard of the old wives tale with the ring? Where you hold it over your belly and if it goes back and fourth its a boy and circles is a girl. Was this accurate for you? With my first it went in circles and I had a girl. It worked with all 4 of my sisters pregnancy. And its neat if you out it over your own heart it says girl. I out it over my belly and it goes back and fourth. Praying its a boy!!!
