Has this ever happened to anyone before?

Last night I woke up burning up hot. I felt like I was gonna puke, we had on one fan in the room but guess that wasn't good enough for me! I had to go to the bathroom and splash cold water on my face, & turn on the other 2 fans. After awhile I was fine an went back to sleep. Thought it was very weird to me bc usually I'm cold no matter what!!! 
Not sure if I'm pregnant  yet but IF I am is it because of that? Hmmm.
I've had symptoms just don't know if my body's playing tricks. Sore breast for 2-3 wks. Super thirsty no matter how many bottles of water I drink. I'm always hot now instead of cold. Very slight cramps that only last a few seconds & sometimes I don't get them at all..
