Last night when I laid to go to sleep i got this horrible feeling on my chest! Like everything I had ate that day was just sitting there on my chest making it hard for me to breath! On top of that I have a cold so my throats is full of junk and it's not helping. I'm 18 weeks pregnant so I called my clinic and they said to go to the hospital and get checked? Should I go or am I over reacting?
