Pencil Test

Bree • I`m 27 yrs old and have one son (8). I just had our second. Not sure if we're done or not.
Anyone done the pencil test? And was it right? My mom did it to my sister and it said girl and that's what she had. She did it to me with my first and it said boy and that's what I had. This time she did it to me and it went all over the place. It was doing circles (girl) , side to side (boy) and diagonal (twins?). Just curious.
