The Nuptial pads aren't white. They're brown or black and look like a mole.

Not trying to burst your bubble or nothing, but they are. Usually dont show until the frog reaches sexual maturity which can be 8 month to a year of age. Some early bloomers will show much sooner at around 5 month. The size of the frog and its growth rate will determine just how soon they'll reach sexual maturity. Has the frog started calling yet?
