Brown spotting while pregnant

Jennifer • Currently trying for baby #2!! 👶🏻👶🏻
I'm roughly 6 weeks pregnant I think (not sure because I miscarried in August, but if I use that as my last period then I'm 6 weeks today). My hcg has been rising and last week it was 12,396.  I have been having brown spotting for about two weeks now.  I'm not cramping or soaking pads.  It's usually only when I wipe.  It is however pretty consistent.  I've read a lot of things that say it could or could not be normal. I didn't have any brown spotting with my miscarriage. Any ideas?  Starting to get annoyed and nervous!
