Hot Flashes

Anyone else experiencing hot flashes ? I’m 7DPO and for the last 4 nights I’ve been getting really hot through the night and I’d have to take off the blankets even with me not even sleeping with anything on. My period supposed to start in 7 days but I’m not sure what this could be. I can be really cold the first minute and then extremely hot the next.

The last time I’ve experienced something like that was with my first pregnancy before I knew I was pregnant but it was a miscarriage. My hot flashes went away after that.
