Welcome to the forum. Thanks for your question.

The chance you caught HIV is extremely low. It is unlikely your partner had HIV, and you used a condom for vaginal sex, and oral sex is safe sex, with little or no risk for HIV. 

You don't say exactly what test was done at 33 days. If it was a 4th generation (also called "duo" or "combo" test), i.e. for both HIV antibody and p24 antigen, then the results was conclusive. Such tests are final any time 4 weeks or more after exposure. The antibody-only tests ("third generation") usually are conclusive at 6-8 weeks, and your result is around 95-99% reliable, still very reassuring. The rapid oral fluids test is not conclusive until 3 months, so that result at 44 days doesn't help very much, although the negative result still is reassuring.

It used to be advised that the antibody-only tests were not conclusive until 3 months. However, that's no longer the case, for the modern (third generation) tests, only for older tests not used very much any more.

Bottom line:  If your 33 day test was 4th generation, you don't need further testing. But whether or not you have another test, don't be worried. You had a nearly zero risk exposure, and even if your tests so far aren't 100% conclusive, they are very close. There is almost no chance you have HIV.

I hope this has helped. Best wishes--  HHH, MD

The first probably was an antibody-only test, i.e. not 4th generation. As noted above, over 95% reliable. The rapid blood tests (unlike oral fluids) perform just a well as regular laboratory blood tests; that result at 6 weeks may have been 100% reliable, or very close.

Between the low risk of the exposure itself plus your test result, you can be certain you weren't infected. But if you remain nervous about it, have a duo test now; or another antibody test (either rapid or lab based) at 3 months.
