HIV screening tests check for antibodies the immune system begins to produce after transmission has taken place. It can take a while for these to reach levels where they can be picked up by current testing methods.

The recommended time period for screening is 3 months (12 weeks) after a potential exposure. However, it is estimated that by one month (four weeks) after an exposure 95 percent of newly infected folks will have enough antibodies present to be picked up by tests.

It would be HIGHLY (and I do mean HIGHLY) unlikely for someone to test negative at 9 weeks and positive at 12.
