a conclusive test result is obtained at 3 months post exposure. with that being said...your test at 11 weeks - 3 days is NOT going to change.
if you are having health concerns, work with your dr...its NOT hiv related.
accept your negative status and move on with our life.
your combination of tests (HIV Duo test at 9 weeks and 11 weeks and 3 days) should prove totally that you are HIV free, HIV Duo test is reliable at 4 - 6 weeks so you have long passed over this line. :)
Congratulations,
in Health =)
