I've been bleeding for 13 days straight. I'm not sure if it's spotting or a period. I had my period from June 24th to July 4th and then I began what I believed to be spotting on July 7th and I'm still bleeding now (July 19th.) I'm really confused about what's going on. I haven't exactly had any cramps but I just really need to know why this might be happening. I'm not on any birth control.
