I had a 4 day period this week it was weird light and it was brown red the whole time. last two days I just had brown spotting.  I used a tampon twice and the rest liners.  Also I was cramping the week before and I'm still cramping even once it was over. Had this happened to anyone? Could it be long implantation?
