Tattoo mistake, hiv?

i dont need a lecture, i just need advice i went to a scummy tattoo party three weeks ago, i saw him change the needle , but not open a new thing of ink i asked my friend and he was like "he always does" im not too sure, im very scared. i developed a sore throat, and a rash kinda thing on my tummy. but that could just be from laying in the sun for hours. i feel like im reallly stressing myself, i will go ad get tested but whats the possbility , i mean he did whipe my tattooed area down with stuff before ad after giving me it, and he used gloves including the fact i did not bleed. whats the porbability ? i havent even had sex yet.
