Can someone help?, four weeks ago I had protected sex with an HIV positive person and my lymph nodes had swollen, I started PEP 8 Hrs after because some pre-*** got in my mouth and it may have been on the condom, the guy said he undectable and he cant pass it along, I took a an oraquick at the 30 day mark which the first one was a weak positive and the second was negative, should I get a blood test?
