Only a 3month test is conclusive?

[BoB9877]

(Risky Exposure Unprotected Vagina Sex)
Exposure : 26/04/08
1 test by oral swap : 21/05/08 (25days after exposure) Negative
2 test by Blood Test : 29/05/08 (4week after exposure) Negative
3 test by oral swap : 19/06/08 (7week after exposure) Negative

i have had a 7week oral swap test and the result is negative, but as what i concern only a 3month test is conclusive rite?

so what are my chance or percentage of being positive at the 3month?

there is a post somewhere in the experts forum, where the doctor has mentioned that he has never seen a 6 week negative person getting a positive after three months.

this is ofcourse for people who are not under any further risks etc. non drug users etc

Sorry i have left this out

before the 7week oral swap test i have my tooth extract 3 day before the test there might still be slight bleeding in my mouth
also drink a can of herbal tea, 20 min before the test
and i use listerine rinse my mouth in the morning before the test
could this 3 situation affect my test result by on the 7week by oral swap?
