Fever at 99. 5, chills, excessive

Hi, I have had chills and mild fever..99.5 maximum for the last two days. Have taken dolo 650. Fever goes. Then rises to 99+ sometimes. Have a bad headache. Chills are there though and I also am sweating excessively although my temp is 99. Feels ironical. I have had pulmoclear for the last ten days cos of fluid in ear and mild congestion. That's slightly better now. But have a bit of mucus in the nasal throat area. Have given covid tests. Waiting for report. Gave CBC crp urine routine and culture. All normal. RBCcount 3.98, haemoglobin 12, absolute lymphocyte 3276. Esr 22. All others normal. Had my menstrual cycle 9 days back. Could the reduced RBC be because of that? Is there any indication I may have covid.. Any advice would help. Thank you.
