Has any one done the wedding ring test? Gender test?

Mafa

My friend is 26weeks pregnant and hasnt found out the gender yet so she done a wee wedding ring test and it came out that she is having a boy.

Has anyone ever done this with their pregnancy and it came out right?

Ino it's only a 50/50 chance but just curious, I'm not really a believer in things like this, but curious! 🤔
