Is being overheated a potential sign of impending labor?

Carrie
I'm 36weeks 3days high risk for early delivery with Hypertension, gestational diabetes and very mild Preeclampsia. 
I've been super hot since last night, not running a fever just sweating all over like crazy. I've had to clean my ears 3-4x because they're sweating on the inside. Even with cool air blowing right on me I'm super hot.
