ring and thread gender predictor test

val • Engaged ??? and expecting our first blessing on april 22 nd ????
Has anyone tried it and has it been accurate for you ? an old wives tale says if you tie your wedding ring to a thread or a strand of hair and hold it over your belly if it swings back and fourth its a boy and if it swings in circles its a girl . you can also do it over your palm or hold it over your heart all three said BOY for me ???? I really hope its correct I find out in 4 weeks
