You have posted on the wrong site.   Questions about HIV belong on the HIV prevention site.  I will do my best to answer your questions with this reply but, if you have additional questions or follow-up they must be on the HIV Prevention site.  Sorry.

You can be confident that you do not have HIV.  Even though your exposure was not protected, your risk is very low.  This is because:

1.  You do not know that your partner had HIV.  Statistically it is unlikely that he was.
2.  If your partner was infected (and he was probably not), your chance of getting HIV from a single act of vaginal intercourse is less than 1 in 1000.
3.  Your test at twelve weeks was at a time when more than 99% of all tests that are going to be positive will be.

When you use these three facts to calculate your risks, they are, for all practical purposes, zero.

Be comfortable that you did not get HIV from the exposure you describe.  EWH
