Ahhh I understand your worry lah! Based on what you're describing, bright area at the bottom and both test lines staying at the top as negative, honestly this sounds like it might be a faulty test strip or the dye didn't run properly, which happens sometimes especially with cheaper brands. A few of us tried different brands and dapat the same issue, so jangan stress dulu! Best bet is try again with a fresh test (ideally from a reputable brand) or better yet, go see your doctor untuk blood test, pastu confirm betul-betul
