scared from doctor

So long story short Im at a clinic because my coworker decided to show up to work with the flu and not tell me until our shift was over, and now Im getting a flu/covid test. Everything was fine until the doctor touched my face, my nose to be exact so she could shine a light in. She had gloves on but she had already touched other surfaces. Im afraid bacteria or viruses could spread into my nose from that or my mouth. She didn't say anything when she did it and I dont think she thought anything of it but Im scared. Like I said she had touched other things with the gloves and especially since it's a clinic Im afraid she touched something contaminated and then planted it right on my face. Im just frustrated cause I went in there for answers and left with even more anxiety.
