Could I have HIV? A month ago I used Grindr a gay hook-up app and met up with a guy.Before we did anything I asked if he was clean he said yes and said he was on prep.  I gave him oral then we used a condom for Intercourse regardless him being on prep and used a toy on me for like 2 seconds and asked him to take it out and I’m freaking out because I got a cold/flu it’s been 4 weeks since. I got tested for HIV through a lab that uses Elisa test 32 days after and it came back negative. Could it be wrong?
