Yep you are right :)
Revised from my other post:
If you see a dark red V (also resembles Y or a W, not lines) shaped vein at six o'clock on your left eye ball its a girl and on your right its a boy. I've noticed its about about 90% true. About 8% of the time that its wrong its usually saying your having a boy when you are actually having a girl. The other 2% its wrong is when it says your having a girl when you are having a boy, you just don't see any V, Y, or a W in either eye or its in both eyes. The reason why I think it is slightly possible to get a false reading is because all our bodies are different and handle pregnancies differently. Women however have actually watched it switch eyes with each pregnancy to the sex this gender prediction test says it will be. Some say its do to the high levels of blood that circulates your body while pregnant and the different hormones your body has from the certain gender. Its pretty cool.
It's not a dumb question. The vein test is when you pull down your lower eye lid and you look for a v made from a vein at about the 6 o'clock position in either eye. If it's in your left eye it's said to be a girl and if it's in the right it's a boy. I hope thats right, I'm pretty sure it is.
