thanks for using health care magic
From the information, i understand you are female?.
Concerning the oral sex
, there is a fair chance of picking up the infection if he ejaculated in you. Semen is a bodily fluid which is known to contain the virus and with a high transmission rate. Protected vaginal intercourse has little or close to zero risk if the condom does burst or semen does spill over.
Concerning the tests, rapid diagnostic tests can only be useful in diagnosing a recent infection as from at atleast three months following exposure.
However, the ab/ag combo is very sensitive and can be useful within a few weeks but two weeks will not really be comfortable. The increase in the index could indicate that there is sero-conversion going on as well as could mean nothing much but related to the second procedure.
However, you will definitely need re-testing in a months time with the HIV
ag/ab combo or in three months time with the rapid diagnostic tests.
Best regards and hope this helps you.
