hiv exposure chances ?

hello everyone.

my story starts off with a couple of my friends and my self going out to a stripclub. i started talking to a girl she told me how she just had a baby almost a year ago, and what not then we went for a dance. well during that dance i started fingering her and she said wait what about the bacteria. i said im clean and she said ok then. and i kept fingering her. i didnt wash my hands for a while after. then it hit me she mentioned bacteria. so ive been freaked out since. i got a hiv test at planned parent hood. and it came up negative. everyone ive talked to said i should be fien that theres never been any cases from that. im just scared. is there a chance that i could have gotten it from that. i always have little cuts on my cutickles idk how to spell it correctly. should i be worried.
