Anyone with spotting on-going??

I've had a continual brown spotting for the past.. week, maybe? It is very small, only when I wipe, or a small amount on my underwear, and it's a yellow-brown, barely coloured. Old blood. I wasn't bothered by the colour or amount, just how long it's been going on :( I've had a little cramping too, but a normal amount from the sounds of it. I'm 5+6 wks.  Anyone else having this?
