Welcome to HCM.
The chances of getting HIV through oral sex
with a female is very very low. You had mentioned that the HIV Test
done on 29-11-12 was negative. But you didn't mentioned when was your last sex contact before the test and what type of sex contact was that? If the exposure was not protected and if it falls within the window period (3 months), then the present result was not valuable.
It is good for you to for another test 3 months after this oral contact and see a negative result for HIV will be safe for you.
