The ring test! Is it true????

So do any of you believe in the ring test? Where you get your ring with a piece of hair and it wings to tell you the gender or how many kids you will have?? I thought it was just for determining the gender. But apparently it tells you how many kids you will have too if you put it over your wrist?? A bunch of girls were doing it at work the other day and it said I would only have 2 boys. But I really want another one so does my boyfriend and it’s becoming hard for it to happen and I’m starting to believe it’s true. It did predict the gender right for one of my friends who was already pregnant and she didn’t know it was a boy and the ring said a boy and when she went for an ultrasound last week they said she was gonna have a boy. Do any of you ladies believe in this old wives tale?? Has it been wrong for any of you?
