Does heat make anyone else sick while pregnant ?!?

I have NEVER been like this before .
My bedroom was freezing the other day , so I decided to get out my heated blanket . Ugh mistake ! I put it on, than took it back off .. just made me feel so sick . I am 7 weeks 1 day pregnant and suffer from morning sickness(just the torn up stomach , not throwing up) all day long ! I haven't worked in a few days I have felt so bad . Today, I got in my car and turned on the heat because it was freezing outside , but had to turn it off too because it as well made me nauseous. I have a pretty physical labor job , and started sweating so.. again... I had to clock out and leave because I feel like death . Is this just me?? Has anyone else had this 😭
