Yes, HIV test results can change over time, particularly if you test too early after a potential exposure. This is due to something called the "window period" - the time between potential exposure and when a test can accurately detect HIV.
For self-tests, which are typically antibody tests, the window period is 23 to 90 days after exposure. This means if you test too early, you might get a false-negative result even if you have HIV, because your body hasn't produced enough antibodies yet to be detected. For the most accurate results, it's recommended to test after the window period has passed. If your first test is negative, you should test again after the window period to confirm the result. Remember that each new exposure requires its own testing timeline.
