Should I go back for a fever without symptoms given my history or can I wait to see if symptoms develop?

On December 28, I went to the emergency room because I had a fever and difficulty breathing. Verdict: Pneumonia. I had a dose of intravenous antibiotic that day and went home with an antibiotic for five days with cortisone in addition to the pumps I was already doing. On January 3rd, it doesn't get better, I go to the clinic. Change of antibiotic for 7 days and 7 days of cortisone. At the end of all that, I was really better. Through all this, on January 4th, I felt strong symptoms of urinary infection. However, I drank a huge amount of water and the next day, everything was fine. So I didn't go to the doctor for that. On January 11, two days after the end of my antibiotic, I had a fever (38.3), without any other symptoms. On January 15, I had a fever again (38.4), still without any other symptom. I still have one this morning (38.2). P. S. All my temperatures were taken by mouth.
