fever symptoms but no fever ?

🍭

i started feeling bad yesterday like i was getting a fever , but had been sleeping a lot . today i decided to go to the doctor , my temp was 99 something so she didn’t think anything was wrong , my skin doesn’t feel hot .. i BD the day before and the day of my ovulation date which was the 5th so i’m trying to see if that MAY be an early pregnancy sign ? since it’s too early to test .
