5 year old sick...on day 2 of illness. Normal sickness or should call MD?

My daughter woke up yesterday sick saying she had to throw up, but only threw up mucus. Throughout the day she threw up mucus 2 more times and then ginger ale once. Her max temp yesterday was 103.3, and even with tylenol every 4 hours, only went down to 100.6 (her lowest temp yesterday). She was able to keep food down yesterday at the end of the day. Now she is up again with another temp of 102.8. Both days she sounds very congested, with sniffing, sneezing and a cough. I should prob tell you all this started with a bad cold, which kept her home from school 2 days last week. But we're getting worse, not better! Any clue what this could be? No snide answers please, this is a 5 year old!
