Sayang, OPK results memang susah nak interpret sendiri, especially kalau you're not 100% sure about the line darkness! Better to snap a photo and check dengan your gynae or go to a clinic, they boleh confirm for you straightaway, no need nak guess-guess kan A few of my mum friends juga selalu confused dengan OPK, so you're not alone! If you're trying to conceive, doctor boleh guide you better on timing jugak.
