ring trick

Mary
Has anyone ever tried the ring trick and it actually been right? My grandmother has always done it too me and it even right with my 2 kids and even now picks up my miscarriage. So I did it over my belly after y miscarriage and it wouldn't move. I feel pregnant but af is due 12/10 so was gonna wait too take a test. But did it over my belly and my wrist and it is showing twins. A boy and girl! 😳😳
