Anyone else?

Am
Hi everyone, 
I am looking for some insight. On Friday the 9th I got a very faint BFP, that afternoon I started bleeding and cramping (heavy like my normal AF
I tested positive again that afternoon and got a positive on a digital.
I continued my normal AF until today (10/14) 
Everyone morning since I have had a BFP test. I went to my doctor and he said it was a very faint positive and sent me for blood work, which I'm still waiting on.
Has anyone experienced this? If so what was the outcome?
Update: HCG levels came back at 131 at 4.( weeks, too low they said.
