Do I need Pep?

Long story short, I have been on Prep for over a year and last week I realized I was completely out of it. I haven't been able to make an appointment for labs to get a new script because of work, but last night I went out and unexpectedly had sex with a guy I met at the bar. I was the top and he was the bottom.

I know the risk for tops is lower than bottoms, but this has been eating at me all day. I have put myself in a similar situation in the past and my health anxiety went through the roof.

Since I have been on it for a year, and I would say that my adherence is pretty good. I might miss a day or two within a week, but usually no more than that. I don't plan on playing with anyone else until I get a new script because I hate being in this situation. Should I be concerned and inquire about Pep?

Thank you in advance for any advice.
