indeterminate western blots w/ undetectable viral load

I had gotten tested about a month and a week after a potential exposure. Week later came back with a positive elisa.. got a western blot. Results a week later were indeterminate. Got another western blot and viral load a week later and it came up indeterminate and undetectable viral load.. what are the chance of it being positive?

Can't tell you chances of being positive because the elisa was before the conclusive window period so it could be a false positive. 3 months since exposure is when an elisa sould be done. If positive then the WB will be conclusive.
