Do I need PEP or I’m over anxious?

I used 2-1-1 prep: 21:20 yesterday I had my first 2 pills, had unprotected encounter at 23:30. Then 3:20 am this morning, I got food poisoning or so, I threw up a lot. I’m worried I threw up the prep

I went to the clinic asking for PEP but doctor told me it was 6 hours apart so my first 2 pills were already absorbed. I’m still worried, should I be worried?
