Pencil Gender Test!!!

I had never heard of this but I found it online researching different countries gender predictor test. I had to give it a try and I am completely amazed by the results I got. It guessed right for my first two pregnancies, saying it were girls which they are. It guessed boy for this one which I'm currently 13w4d (but idk the sex yet) and if I get pregnant again it will be a girl and that will be it for me. I did it to my mil and it gave her two boys which she has and two abortions, which she also had and it predicted it in the correct order. Anyone else done this test?? What have your results been like?
