shortness of breath

Gayle
Anyone else experiencing this? 
started last night to the point i think i had a panic attack. 20-30 mins of me trying to gasp for air and going through petrified tears along the way.
Tonight im breathless again but think its just my lungs being squashed by baby and the food ive just eaten... does that sound possible?
I dont want another scare like last night so just looking for some other points of view 
thank you in advance
