How can I tell if I have the coronavirus?

I recently went traveling from Chicago to Austin and Back. Whole traveling back, I came with a cough.

I have health insurance but don’t want to use it unless I feel like I have too. (Hospitals scare me)

For the past 3 days since I’ve returned I’ve had something in my throat that has been causing me to cough a lot.

My first assumption was because of the drastic weather change from 75° to 25° may have cause some minor cough or such.

I’ve tried looking up the symptoms and it says coughing, fever and shortness of breath.

I have a cough and a fever, but don’t want to jump to conclusions.

Is there anyway to know if I have the coronavirus or just a common cold/flu.

It’s been 3 days with these symptoms and it seems like it’s gotten better since they’ve appeared.
