Aihh sayang, better check with your doctor first sebelum buat urine test, spotting yang tak jelas mcm tu memang boleh ada many reasons, bukan mesti kena tunggu period dulu. Few of us dalam group pun pernah experience spotting yang random, some turned out hormonal lang, some ada other reasons, so doctor can advise you properly based on your situation. Jangan stress dulu, just get it checked out to be sure!
