Needle and threads old wives tale?

Y'all I'm going crazy over here. How many have tried this? All my family has tried it and it's been 100% correct. My husband and I did it and they were the exact same, girl, girl, boy, girl, girl, boy. We've been TTC for 9 months and he's about to deploy in a few days so we're going insane this TWW. They say if you hold the needle over your belly and it doesn't move, you're not pregnant and if it moves in a circle it's a girl, line it's a boy. I hold it over and it goes in a full on circle and I am supposed to have a girl first. Anyone done this and it be accurate??
