I'm worried about my decreasing WBC. Actually its more of HIV fear. My last exposure was on 26/04/2014. Went for HIV ag/ab testing on 15/06/2014(50days) and 05/08/2014(101days), both non-reactive. However, my WBC is decreasing; WBC count was 10+ on 15/06/2014, 9 on 05/08/2014, and 7.9 on 30/08/2014. What's your opinion/advice?
