Evaporation line na lang po yung nakita nyo sa gabi. Pagka start nyo po ng pt, you only have a few minutes to wait for the result (depende sa pt, nasa packaging po yun kung ilang minutes bago icheck ang result). Any other change beyond that time period is unreliable na po. You can wait for another week po siguro and try again if di pa rin po kayo sure. Kahit 2 na pt na para sure.
try again sa morning sis after a week. yung first pee mo sa umaga para concentrated
