Faint line/ 0 HCG

Hi,

I was wondering if anyone has had more than one faint line pregnancy test.

I had 3 faint lines a few weeks back, then AF came which I assumed meant that I had a chemical pregnancy. Then I went to my doctors and had bloods taken(1 week later) but the bloods didn't show any HCG levels. I am so confused by this as it seems to much of a cosidnance that 3 test had positive readings.
