🤰🏻👶🏻?!??? Help.

I’m 6 days late for my period . I’m always ontime , always on the 17th it never fails . I’m currently late , I’ve been nauseous all day , acid reflux has been acting up , my boobs look bigger They also randomly hurt a little , my body temp has gone up but not fever hot , just feel warmer then normal . I took a test yesterday or the day before and it was negative . I’m so confused .
