Things don’t feel like they did before

This is my 4th pregnancy I have 2 boys and 1 girl and with all my other pregnancy’s I never felt like this during my first trimester I feel constantly anxious, short of breath, extreme fatigue, light headedness, and nausea with no vomiting … pretty much everytime I get up and try to do anything I feel absolutely horrible it’s freaking me out like something might be wrong with me this time around my baby’s heart beat was good and my vitals where good at my OB appointment but I just don’t know has anyone else had symptoms similar to these especially the shortness of breath any advice?
