Ingin tahu. Test OPK

Eh memang macam tu lah OPK sis, especially kalau line terang dari CD12, means your body dah start producing LH surge, so it's gearing up for ovulation! Biasanya the darkest line is when you're most fertile, so next time try to test twice a day around that time (morning and evening) so you don't miss the peak, a few of us dalam group chat realised ni the trick, otherwise memang boleh terlepas the best window. Don't worry, first time using OPK memang confusing sikit, but you're on the right track!
