Wedding ring gender test

I've been looking up information about this little wives tale. Apparently many people think it's accurate. I've done it on myself since I've recently found out I'm expecting. I want a daughter so bad as I have 2 sons already and everytime I do it, it spins in circles (distinctly) but according to which post you read spinning in circles means a girl and moving back and forth means boy then your read another post about it and it says just the opposite back and forth a girl circles a boy. Anyone ever tried this out? How accurate was it and which one do I believe since my ring is going in circles? Lol
