Is this a faint positive??

Had a miscarriage in June. Did serial hcgs to see the decline. Bled for 1 month straight with miscarriage. No period that I know of after MC.  Feel like I had implantation spotting. This is my test. Tried to enhance with the apps not sure if there is a positive or not. So confused about all the issues that can occur with testing. I've heard about evap, not sure if that is what I'm seeing.??
