10 Week Test Negative w/symptoms

So I just tested negative Oraquick Advance at 10 weeks after an unprotected incident - this was after experiencing some symptoms for over a month. I tested in Mass. where the window period is 6 weeks.  Can I trust my negative results?  The tester said the test is so sensitive that it picks up infections in as little as 2-3 weeks and that I did not need to test any further.  I was also told that if I had been experiencing symptoms for over a month, I would have produced antibodies.  thanks in advance for your input...

3 months is conclusive...but it is HIGHLY unlikely that a 10 week test result would change.
