Sayang, OPK positif tu bila test line sama gelap atau lebih gelap dari control line, tu means your LH surge is happening and ovulation coming soon! Kalau first time confusing, a few of us mums keep the test strips side-by-side to compare, or use digital OPKs yang lebih straightforward. Best time to test is morning urine, and try to be consistent dengan timing each day so you don't miss the surge. Rooting for you!
