Am I at risk?

I am aware on the main ways HIV is transmitted, but in my case it's something different than those three but I am still concerned over this. My old friend used to cut her own arm with shards of glass, and around a minute or so after she had done so I was carefully picking up the pieces when one of them jabbed me and left a little cut, instantly I flipped out, because I did not know which edge of it she had used. Later that day, her arm that had cuts (not actively bleeding... but that just been cut earlier in the day) brushed right over my cut (same deal as hers) and I freaked even more. She was a virgin but I can not be sure if she had it or not, as she may have been born with it etc.. assuming she had it, would I be infected in this way? Thank you... pls help

Thank you- i'm going to add something, regardless of if it changes anything, when i put brush, i mean like a rough scrape against them, does the answer remain the same?
