Eyes tearing? Nausea worse in cold?

I cannot figure out if this is the pregnancy or maybe I am getting sick... I've never been at this stage of pregnancy in the winter... so I don't know... Is anyone else having these two symptoms...?

1. Cold makes nausea worse?

Is anyone else (who lives in a cold region) experiencing extreme intolerance of the cold? My nausea becomes unbearable whenever I have to go outside... even just long enough to run to the car, buckle in the youngest and start the engine.
