Protected Sex with a Sex Worker at a "Massage" Parlor

Long story short, I had some drinks last night, was feeling a type of way and visited a "massage" parlor before going home. I had protected oral (receiving) and vaginal sex with one of the workers, where I THINK every thing about putting the condom on was done properly and it didn't rip or anything but at the same time she was the one who put it on and I was drunk so I can't be absolutely 100% sure and I have absolutely no idea if she is tested regularly or if she has any sort of STIs.

Now sober me is paying the price with a whole day of anxiety thinking of worst case scenario getting HIV which led me to go to the ER and get a PEP prescription which I started within 24 hours after potential exposure and plan to get tested shortly after I'm done with that.

How likely is it that I actually caught HIV, I already know the statistics that even if she did have it, if you were using a condom then its really unlikely you contracted it but I just can't stop worrying. It also was a more upscale spa not one of those sketchy Asian massage parlors. I live in Ontario Canada where sex work is decriminalized so it's legal to sell. Are the girls at these places tested regularly? How likely is it that I'm fucked.

Also I'm not nearly as concerned about the more common STIs that are curable, if I got one of those, it is what it is and I'll just get the treatment/medication for it. I'm mostly concerned about HIV specifically.

Question summary: Is there anything else I can do? How much do I actually have to be worried about, it was my first time with a sex worker and DEFINITELY won't be doing it again. I know it was an absolutely stupid decision, but nothing I can do about that now.
