I only left my house 2-3x in 4 months. I dont go to crowded places. Im a week from my period and I felt hot, got to check my temp. it was 37.5 celcius. I wasnt able to sleep the whole night cos I was monitoring my temp. Thank God it went down. but the whole day felt sluggish. I feel like I have a fever but I dont. I have the mood to eat food, I can smell, taste etc, no cough, no shortness of breathe just low grade fever last night.

Is it possible its pms? :(
