Your chart says girl for me! haha I don't like it.. says that I am 36!!! LOL
ok, one of my all time favs is the ring test...
Get your wedding ring (or other ring/needle/pin) and attach it with a strand of your hair or some string. Lie down and dangle the ring over your belly. If it starts moving in circles, you are having a boy, or if it moves like a pendulum from side to side, then you are having a girl.
Mine swings FRANTICALLY up and down. No circling at all.
I also used to do this test when I was a kid, over my hand, first, it would swing back n forth for a boy, then it would circle, then it would stop dead. Curious to see how accurate that's going to be!!!
