Symptoms can't be used to diagnose HIV so you should stop examining your body and keeping track of what you think are symptoms and quit Googling symptoms cold turkey. Then you can relax.
Just brushing an open cut against someone else's blood can't transmit HIV because the air effectively kills it. Even to be a theoretical risk would require deep gashing wounds with the virus thrust deeply inside both people's wounds, and that didn't happen. You are safe.
Only non-sex risk for hiv is sharing hollow needles that you inject with and you were a long ways from that.
