I am SO sorry for all the additional context thats needed here but:

I have had severe anxiety about getting Covid, and since I was eligible to get the vaccine in my state I was eager to sign up.

I went to get tested the day before going to get vaccinated.

While at the testing cite, someone who was: \~10 feet away from me in line, outside, with a mask on, while I had 2 masks and a faceshield, for a total time of aprox 1 min; mentioned that they had "a lot of symptoms and probably had covid"

About 10 hours after I get the vaccine I feel just mildly malaise and I take my temperature, it reads 98.8. I start having a full blown panic attack thinking this means I got covid from the person in the line. As this is happening, and about 3 subsequent times when I have a moment of really high acute panic, I take my temperature again and it briefly goes to 99.2 (but only for a few seconds, any time it rose, I stood up and got some water and took some deep breaths to calm down and it went to 98.6 or 98.4) As of the next day, my temperature has been between 98.2 - 98.8, but again it rose to 99 for 1 second, but upon calming down and re-taking it was 98.2, and I had no other symptoms the entire duration.

I have ordered a Covid test that I'll be taking on Monday, cancelled my work hours for this week, and am isolating from my family. But I am also getting so incredibly anxious while I wait. I guess my questions are:

Is Covid a realistic outcome given how brief and the safety precautions involved when I was potentially exposed?

Does anyone have stats/info on if the first dose of the Pfizer vaccine can cause a mild temperature +0.02/+0.04 increase like this?

Does a temperature of 98.8, or 99 but for &lt;1 min qualify as a fever? (especially if its only for a period of half a day)

Thank you so so much to anyone who bore through this anxious rambling, and I really appreciate anyone who takes the time to read/respond! I'm sorry for rambling but I've been anxious to the point of feeling like I'm constantly about to faint its so bad.
