Chills and hot flashes

Has anyone had chills and hot flashes as an early pregnancy symptom? At night I get really intense chills and throughout the day I’m getting big hot flashes.

I’m not sure exactly how many DPO I am, but I believe in somewhere between 6-8 DPO. I’ve been having these chills and hot flashes for 2 days.

I’m also having constant mild nausea and food aversions very similar to how I felt when I was pregnant with my son, but I definitely didn’t feel these symptoms this early last time!

Also: I don’t have a fever, I know chills and hot flashes are common with fevers.
