Hot flashes in 3rd trimester?

Is it possible I’m having some sort of hot flash type things?

I’m 31 weeks and keep getting overheated and opening windows when it’s like -22 lately in my state..

My man keeps saying it’s just me n he’s cold.. but we’re in a huge appt building and live on 3rd floor so I thought maybe heat was riding up from other spots? Idk lol..

My bf is also from a tropical country (Croatia) so didn’t know if he’s just not used to anything but hot? Lol..

Probably just me huh?
