I wouldn't depend solely on the intellegender I have read and heard that this can give false results more on the boy than the girl….
Get a purple cabbage, boil some water, cut up your purple cabbage and simmer your cabbage for 10 minutes, mix the same amount of urine as cabbage juice and if your color changes to magenta or lighter then it's a boy, if it stays dark purple it means girl. This worked for me, and it was spot on.
