I had sex with a prostitute 9 weeks ago. It was vaginal and I was wearing condom and condom did not rip. She did however perform oral sex on me with no condom on, I did not perform oral sex on her.
At about 2 weeks I started feeling something in my throat like something was squeezing my lymph nodes. I started googling (worse mistake of my life) and got myself thinking about HIV. I did got to the doctor at 2.5 weeks and asked to get test for all the STI's and all came negative including HIV. Then I got test for HIV at 4 weeks and 7 weeks with the rapid HIV test and they both came negative as well. Doctor also tested my blood for the CBC (complete blood count) and once the results came back he said it was low pointing towards me having a virus in my system (it's flu time so not sure what kind of virus it was or is).

I got my lymph nodes looked at and they are not swollen and I have no other symptoms.

Should I be worried? and should I get re-tested again at 12 weeks.

Thanks for the help.

Thank you for your inquiry. From what we gather from the question, you were asking about the risk of acquiring HIV from protected vaginal sex and the conclusiveness of your test results. From the information given, this scenario is determined to be Low Risk. Evidence of transmission occurs through these activities when certain conditions are met (E.g. Vaginal sex with a condom due to improper use and potential breakage of the condom)

In order to contract HIV the following conditions must be met:
There must be HIV present in a bodily fluid. The five bodily fluids that carry the HIV virus include: blood, semen (including pre-ejaculate), vaginal fluids, breast milk, and rectal secretions.
The bodily fluid containing HIV must have direct access to the bloodstream. This can be through cuts, tears, rips, mucous membranes, open sores, or needles.
Transmission occurs through a risky activity in which the first two conditions are met. For example: condom less sex, sharing needles, unsafe tattoos or piercings, vertical transmission–from mother to child (in utero, during delivery, breastfeeding).
The scenario mentioned above meets the two components of the transmission equation as there was an exchange of body fluids and direct access to the blood stream via mucous membrane.

The symptoms you are experiencing could be due or explained by other illness or causes. Because HIV tends to mirror other viral infections testing is really the only way to know.

The Rapid Test looks for antibodies that the body develops in response to an HIV infection. The window period is 4 weeks to 3 months with up to 95% of infections being detected within 4-6 weeks. False positives are a particular concern with rapid testing .One study suggests that rapid test may miss up to 12% of acute HIV infections.[1] According to the Centers for Disease Control and Prevention (CDC), up to 8 percent of HIV-infected people can have a false-negative result when oral in-home tests are used. The 4th Generation EIA (DUO) Tests looks for antibodies and P24 protein. Antigen (ag) test- P24 is detectable immediately after infection, & only for the first few weeks. The antibody (ab) test has a window period of 4-12 weeks. Most HIV specialists consider this "DUO" test conclusive at 6 weeks., with 99.9% accuracy. Canadian testing guidelines recommend re-testing with any HIV test at 12 weeks.

Recommendation: Refer to Physician for HIV re-test at 12 weeks.
