My period isnt due till today or tomorrow the 8th or 9thnot and since the 5thi ive had light bleeding of red and brown. I dont have any pads so ive just been using tampons and it hasnt filled any. It goes from being there and giving me a few drops to hardly even noticeable. If i am suppose to get my period tomorrow could i test in the moring if i dont start bleeding heavily? Or do i need to wait til bleeding is completely done before i can get a positive hpt?
