hiv testing

this may sound stupid, but i have been so paranoid about hiv.
i took duo 4th generation combo tests at 1st week 2nd weeks and 3rd week all negative

at 6 weeks i took a hiv rapid test, it was a finger ***** blood rapid test. I dont know what kind of needles are used in ontario. Can those automatic i guess single used be accidentally used again? Can I get infected this way? . Please help me I went there to get peace of mind now i am even more worried are there any risks? is there a possible by mistake a nurse used an old needle (green color). if an old one was used what are the chances of getting hiv.also my test was negative then again went for another rapid hiv test after 8 weeks of my exposure low risk ( oral receiving sex)and i used a condm of veginal sex. it cam back non reactive..this time i went to a different clinic, the nurse opened the testing kit in front of me. my question is the needle that came out of the kit, which was used on me was a different kind of needle that was used on my 2 weeks agothis time the needle was thin and in green colour, and the last time that was used it was in blue colour and bigger. also as i remember in last test the needle was not in the box the nurse had it separate. its just that after 2 week of the test i m starting to develop symptoms, now i know i didnt catch hiv from the exposure but i m started to think i migh hav gotten it while doing a test
now at my nine week i m getting really sick….headeace, vomiting, nect pains etc…my doc think its a sinus/viral infection put me on antibiotics
the only time I'm worried about is when i went for my test at 6th week. the needle was not in the kit, nurse had it separate, i m no blaming anyone, the nurse was v nice my question is how much blood is required to get infected and how soon the virus dies on the tip of a needl
is 8-9 weeks too late for initial hiv symptom
what are the chances of 8.5 week results changing..
does all the symtpms always have a fever..

Hello,
Thank you for your post.
The fingerprick device used for the Insti test is single use, disposable and sterile.  Once used, it cannot be used again, because it has a spring device that.  It is impossible to re-use it once it has been used.  Therefore no need to be concerned about that.
In any case, you ddi not put yourself at risk of HIV infection in the first place as you only received unprotected oral sex.  Bearing that in mind, and the fact that you have had all those negative test results, we can conclude that you are HIV negative without any doubt.
Best wishes,
Dr José
