or maybe just a week shy of 3 months? I had unprotected oral sex about 8 months ago. july 05. and i was tested in mid october. ( i wanted to wait to make sure.) and the test came back negative. so how likely am i to have contracted HIV after getting tested? and even if that was a negative result. how many more times should i get tested before i know 100% that im not infected. I read that it can take up to a year before the body starts to show antibodies for HIV.

If you were 'receptive oral' then there is no risk of HIV transmission. If you were the person performing the oral, and if there was no ejaculation, then, again, your chances are remote. However, since you've tested at 3 months it is highly irregular to consider the need to re-test unless you've had another exposure. However, and this is a big HOWEVER, you need to do whatever it is that will bring you peace of mind. chris

Yeah, i need the peace of mind, because lately. Ive had both white tongue and pain around my armpits. plus i know the specific dates that i fooled around with that girl. and when i had the test. so the incident happened on the 14th of july. and i was tested in late october.. on the 25th.

As Chris said, the risk of transmission via receptive oral sex is threoretical at best. In other words, you have a better chance at getting struck by lightning than by contracting HIV via receptive oral.
In regards to your "symptoms" - don't pay attention to them. What you described is not indicitive of seroconversion. So don't chalk up every sniffle, scratchy thoat or anything else to pointing to HIV infection.
The vast majority of people will produce antibodies that will show up on an elisa test 4-6 weeks after exposure. 13 weeks is considered conclusive in testing. As you have tested negative at this point, there is no reason for you to retest or to worry (a day or two short of that benchmark is irrelevant).
Since your sexual encounter poses only a theoretical risk and you have tested negative within the proper guidelines, you are free to move on.
