See, normally we do not label a temperature of less than 99 °F at any time of the day, as fever. So first of all, we need to know if the patient is really having fever or she is just feeling feverish, because unnecessarily giving PCM/Crocin can be harmful. It is such a great move that you are regularly charting temperature, continue doing the same. And if fever is more than 99.9°F , just go for a lab work up. Take PCM round the clock.  Drink plenty of water.  And if fever presents, take a minimal antibiotic like Cefixime 200 mg x 5 days. And start the lab work up.

It is advisable to give her a mild antibiotic cover - which will help to reduce the fever if it is due to some infection. You can look at giving her Tablet Augmentin - this won’t be available OTC. Please consult a doctor for a prescription. If situation still doesn’t improve after 1 week, go for basic blood work.

It's ok. Take adequate diet and plenty amount of water.

These temperatures are normal. No further treatment needed.
