Could this be strep? Or something else?

Her throat hurt more yesterday am when there was no sores. First pic last night, still sore but not as bad, and 2nd pic now, still kinda sore. Doc is booked for days. Just wondering if we should head to urgent care vs going to school.

Edit: no tonsils and nothing on roof of mouth, seems to be centered around uvula, no fever, only stuffed up
