Hello, I’m A Healthy 58 Yr Old Female On Thursday

Hello, I’m a healthy 58 yr old female
On Thursday this week I started experienceing symptoms similar to the flu. I’m in Maine so I’ve checked for ticks.
The last two days I’ve had a bit of blood in my urine.
I’ve had about 4 pkgs of emergency-C in the last couple of days. Hoping to treat symptoms of flu. I have a fever of 100.3
What should I do. I’m here in Maine with the family I work for
so, I don’t have a Dr. here. I work for an elderly couple and don’t want to infect them with anything. Suggestions? Thank you!
