Question about having sex with someone on prep

I had sex with 2 guys who were on prep. The first guy topped me and came in me. I hooked up with the 2nd guy 2x about a month after. Both were on prep. I know this because the first guy offered to show his papers and the 2nd guy showed me the actual pills.

I myself am not on it. My question is if I should be worried about getting HIV? As in is there a likely chance I have it?
