10 days old big cut on my scrotum and hiv prevention?

i know its kinda wired but it scares me a lot...so please help me with this...i had this genital warts on my scrotum and i my doctor burned it with lazier. it was a big deep wound there around 1cm...10 days after i had protected sex with this girl who told me latter she used to have chronic leukemia!!!! it scares me a lot even tho she said she don't have HIV or any other STD...i have condom but my wound was open and it was not dry yet! no bleeding and it was still producing scabs. for some reasons i decide to put 2 layers of Muller M tape on it before and it was there all the time on my scrotum! i think the tape was in touch with her vagina fludes but i don't think it passed the tape....so my question is how much risk i have to be victim of HIV! im in 2 week period after the exposure and i have no symptoms! but it still scare me so much and i cant take it of my mind so please help!
