Western blot and tridot. Lab results?

After 8 to 10 years of potential exposure i feel like i have aids symptoms. So i told my doc and i got tested using tridot. It was negative. However i was nt satisifed so i got tested using western blot and it was negative. Reports are negative but there is mild pink line in the paper. I asked the doctors who said the report is fine and that line is nothing. But arent western blot papers supposed to be clear? The lab says im fine and it is negative. Even my doc says im negative. The other doc said my report is fine but if im in doubt,he asked me to do pcr rna test. My symptoms are persistent with little improvement. What do i do? Can i believe in the lab results? The pink line doesnt look like a band but it is horizontal and it is 3/4 distance away from the control band. I think near gp40 region. It doesnt look like a band tho.
