is this hsv?

i keep getting this pus in the center of my lip every couple of weeks and i never tested positive for hsv1 or 2 ever in my life… the first time i got it i accidentally wiped my lips and it was crusty like a hard ball that came out. the second time i got it a month later it was more pus than crusty. and it leaves a small hole in my lip that seems to re fill.
