Piercer used a piercing gun and now I’m anxious

I feel silly for not doing more research and just going off my family saying theirs where fine. And I stupidly assumed most people used needles to pierce

Anyway I got to the place, sat down ready and she pulled out a gun, and I wanted to tell her to stop as I’ve heard guns can be risky but I was so anxious and I didn’t want to waste her time with coming up.

So I got the piercings and now I’m walking around anxious that I’m going to get a massive infection or something:((
