Hot Flashes and 6 DPO

Samantha
Soooooo I am 6 days past DPO ... I have never had a hot
Flash before ever!!!!! Today out of no where I had to open the windows, turn on the fan, take off my shirt and fan myself with my hands!!!!!!!! Could this be a possible sign of pregnancy ?!?!?! I am not trying to get my hopes up but just wondering if anyone else experienced this?!?!
