Need your thoughts?

Okay, I had a normal period that seemed to almost go away and then it picked back up to bright red spotting. So, i've had bleeding at some leval for 15 days now.
I took a clearblue digital test and it said I was pregnant today. I went to the doctor and my HCG is only 6. I am going back to get more blood work done on saturday to see if it rises or not.
First off, I was quite suprised to get a positive home pregnancy test with an hcg of only 6, but i'm worried about the fact that i've been having all this bright red spotting for so long.
I know there is a posiblity that I might be in the process of miscarrige, but I was wondering if any of you had any thoughts.Need your thoughts?
Go to the a DOC!!!!U shoulnt be bleeding like that......
see your doctor
