Should I be concerned?

Tia

Yesterday I started spotting, I’m currently 8+5. It started off as a reddish orange color, then turned to pink & today is now brown, I’d only see it when I go up to wipe, I haven’t really cramped, just a bit uncomfortable. Last time I bled I was about 5 weeks or so, I’m worried but not sure if this is normal or not. I can’t get in to see my OB until Thursday, my next option was the ER just to get some type of peace of mind, any thoughts?
