Was My Third HIV Test Necessary After 8 Months, And Are The Results Reliable Given The First Two Tests Were Negative?

I had 3 tests. First : PCR test on 10th day after contact(The one that gives you answer in couple of days). Second : Rapid Anti HIV 1/2 test after 3 months. Third : Rapid test after approximately 8 months. All results were negative. Reason behind my third test was that I found 5-6 molluscums on my arm. I got scared and got tested couple days after I saw it. Don t know when it appeared but as soon as I saw it, waited couple of days and got tested with rapid test. Result was negative. I may also have gotten molluscums from my wrestling training but still, I m anxious. Did I get tested right? Was 3rd test in reasonable time(Do rapid tests work after 6 months is passed)? Some people told me that first two were enough to say I was negative but I m still anxious. I had doctor remove my molluscums.
