Actually it's the other way round. Tests don't give false positive, they only show positive if they detect HGC which they won't if you aren't pregnant. A test can give a false negative if it's not sensitive enough to detect the HGC in the very early stages.
As for the bleeding, that doesn't necessarily mean anything, I bled with my second pregnancy.
I suggest you get yourself checked out by your doctor.
