Would you go to the hospital?

Ok.. so I'm not one to run to the Dr or ER for every little thing. But all day today I've had lots of pressure down low and extremely tired. Baby moved around and some of the pressure went away. I came home from work and sat down since I still felt exhausted and all of a sudden I got some shooting pains in my chest that shot up through my right shoulder and down my right arm. It hurt if I moved wrong so I figured it was a pinched nerve stretched a little and drank some water. Ever since then my head has been pounding and I'm absolutely freezing. Is this all connected or am I just paranoid?
