Im 8 weeks too and spot off and on. But its not bright red! Its scary. Just keep an eye on it.
I've been spotting since i got my pregnancy test. It's starting to lighten up as I'm in my 8th week. But it's scary try to just relax and enjoy each day. I'm forcing myself to stay in the moment. Good luck
Yes its old blood. Be alarmed if it is bright red blood :)
