Cold??

Anyone cold all of the time? Im 6 weeks pregnant and always cold. I was never a cold person before. (I ran my AC year round) Now i find myself using my blow dryer to warm my feet and legs several times during the day. I don't believe that could raise my temp over 100...or could it? Doesn't seem like it because as soon as i turn the dryer off i start getting cold again. It's the quickest relief to the cold feeling though.
