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 and me not realizing I had a cut on top of my mouth. then we used a condom for Intercourse regardless of 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 and fatigue/body aches it’s been 4 weeks since. The symptoms of the cold disappeared now it’s just body ache and fatigue. I got tested for HIV through a lab that uses a combo Elisa test 32 days after hooking up and it came back negative. Don't know if me being really anxious is causing symptoms I'm worried . any advice.
