Oh boy...
This test is a scam, scam, SCAM! 
Don't waste your money!!! Take a look at all the Intelligender threads just a few below this one and you'll see everyones (including my own) WRONG results. I took mine in the time frame and did everything right. Got a boy result...I'm having a girl.
It's just a silly PH test. There is NO WAY that urine can determine gender. If it was possible, they'd be selling these kinds of tests everywhere. Go into it to have fun, because it's got a 50/50 shot of telling you the right gender.
