Another day of spotting

I am getting worried, I saw more brown spots like chocolate and a bit of blood. I feel my vaginal/uterus having sensation like blood flowing out, only it does not stain my pad at all. Although it is good news, but I am still worried on seeing a negative hpt. I decided to perform one tomorrow morning so that I can put my mind at ease on what is happening. If it is negative, then I look forward to Day 12 of my cycle again. If it is positive, then I should visit a doctor on Friday.
