Aiyooo sabar dulu lah, OPK line yang samar-samar tu memang bising jugak interpretation-nya, kasi few days lagi then test again sebab sometimes timing je off hehe. Tapi kalau dah 2 minggu lewat and you're worried, better go see your gynae to confirm everything is okay, could be hormone fluctuation, stress, or something else yang doctor boleh check properly, so you can stop guessing ye.
