Sayang, ni memang confusing situation! But please lah go see your doctor or klinik as soon as possible, cokelat discharge campur period after positive test needs proper check, okay? They'll do an ultrasound to see what's actually happening inside. A few of my mum friends had similar scares (spotting, unclear lines, timing yang pelik) and it turned out to be different things, some hormone-related, some other reasons, so really kena confirm dengan doctor, bukan guess-guess. Don't worry, tapi jangan delay the check. Lepas jumpa doctor baru clear!
