Expert Q & A Answers About HIV antibody test

My HIV antibody test is positive...but the Western Blot is negative. What does this mean? Do I have HIV or not?

About 7 months ago I visited a gentleman's club in Singapore (I was there for school). I wound up French kissing one of the workers there. I did not have sex ⎼ including oral sex ⎼ and no drugs at all. I got concerned about STDs so I went to a doctor for advice. He said that French kissing is a risk for HIV and I should get tested at 3 months...but I got scared so I got tested almost every week. And all ten tests were negative until my last test at a hospital. That test was an ag/ab test called a chemiluminescence test and the document they gave me had an index number on it (2.69). They ran a Western Blot for HIV-1 and HIV-2, both of which were negative. I went back for confirmation two weeks later and got the same results but with an even lower index number (1.72). I’m so confused about these results...but I also read that false positives are rare...do you have any advice?
