“HIV/AIDs?”

So, about a day ago I felt this pain in my index finger at work and I saw it was a tiny brownish line in my finger. I’m not sure where it came from but every time I brush my finger against something it hurt it feels like a splinter. So, when I got home I went to remove the splinter with a nail clipper but before I poured cleansing alcohol on the nail clipper and my finger. When I went to clip into my finger I saw a little bit of dried blood on the clipper. It was a dark red. My finger wasn’t bleeding or anything because I hadn’t got inside of my finger to the point where it would start bleeding but it was someone else’s blood. Am I at risk for HIV? I’m so paranoid.
