HIv Report conclusion. Non reactive?

Hi Sir, I had sex with unknown girl without condom, the next day when I woke up and see that lots of blood on my bed and my body. I was shocked and the girl told me that she was in menstual cycle (monthly period). I was also not aware about this  because I did drink. 1) After 1 month I did HIV test and report says 0.26 - Non reactive, so "what is the meaning of 0.26 present and says non reactive?" 2) I did HIV test after total 80 days risky sex date and carried out test from diff. Lab and result seems only non. Reactive. Even Syphilis test also non reactive. But sometimes I feel hives and burning sensation like tingling and sting on my hands since 1.5 month. Please let me know  risk is there and appreciated for your kind give me answer asap. Awaiting for your support
