I'm really concerned about my HIV status after having an unprotected encounter with a sex worker. I've taken several tests: an HIV Antibody Test at 21 days and at 2 monthswhich were both negativethen a CMIA Method test at 12 weeks, and a Rapid Test at 3 months. I also did a CMIA test at 20 and 22 weeks, and all these were negative too. Are these results considered conclusive? I've been experiencing some issues like recurring colds, muscle and joint pains, and low levels of Vitamin D and B. Could these symptoms mean something? I'm just worried and would appreciate some guidance.
