Hot flashes

Megan
So question has anyone every felt with hot flashes as either a Pms symptom or a early preg symptom? I am due for my period on the 28th and I've been hot as all can be. Even laying on front of the ac I still feel warm. Never had this for pms so was wondering if anyone else every had it. 
​Between feeling hot and being exhausted all I want to do is sleep on the coach in front of the ac. Which is so not my normal.
