Chills/ goosebumps? Brrrrrrrrr!

Lexi • DD is almost 2.5yrs and we are due with #2 on Christmas.
Is anyone else experiencing ( or did experience) this?  Its 85 degrees out, i have no AC on in my office and all day long i'm freezing with goosebumps and all my arm hairs standing on end... 
​( my hpt's are ambiguous right now. I'm 3 days late). 
​Chills anyone?
