Random pregnancy quirks.

So as my pregnancy goes on I've noticed more and more my body has "quirks". Yes I went through health class. I know the changes my body is going through. However I am baffled by the fact that since I have been pregnant I am cold 24/7 all the freaking time. Lately I've noticed my body isn't registering heat as it used too. For instance I took a shower using hot water alone and it still felt too cold. Only reason I knew I had to turn it down were my feet turning bright red. So I ask is anyone else going through this. 2nd time moms did you ever go through this. I did call my pcp and left a message as I was just there yesterday. But honestly wanted moms to be takes on it.
