Which ones do you know? Any that you swear by?

Chinese gender chart hasn't let me down yet. Neither has the good old ring test. But there's one I was taught by an old voodoo lady in New Orleans. Its similar to the ring test, except you hold the ring over your left hand. It tells you each baby's gender in your lifetime, including angel babies lost. Mine: boy girl boy girl and then boy and girl swing together like it can't decide. What do I have? Boy, angel baby lost at 9 weeks, boy and well we don't know yet (too early). I tend to be superstitious but hey! Its right so far! Haha
