Got First BJ and Worried

I had my first blowjob from an erotic massage parlor. It only lasted a few minutes and she gave me a rim job very very briefly too and no protection was used. Yes I know I should have but I honestly didn’t know it was happening til it happened, we went from a table shower to just her sucking my dick.

It’s only been a couple days and I feel fine and they told me they’re all clean and get tested every 2 weeks but that could obviously be a lie.

What should I be on the lookout for in the coming weeks and should I get tested? If she did have anything, is the transmission rate 100% or what are transmission rates like? Just panicking and the most info I can find anywhere is basic stuff they teach you in school
