Ring and thread gender predictor test

Theres an old wives tale that says if you tie your wedding ring in a strand of hair or thread and hold it over your belly , if it swings back and fourth its a boy if it goes in circles its a girl . ( the mom has to do it not the dad ) the results for mine were boy . you can also hold it over your heart and your palm all said BOY for me ?? Has anyone else ever tried it and was it accurate for you ? I really hope mine ends up being correct
