Its conclusive dear. The window period is the point from first infection until the test can reliably detect antibodies in the blood. For the ELISA test this window period is 4 weeks to 3 months. A 4th generation test like the one you took, also known as a DUO or Combo test, looks for both antibodies and P24 protein antigens.
