Sometimes it gets hard to breath and i have to breath real heavy to feel like im getting a breath at all. Its worse when im laying down or sitting. But when i stand up i get dizzy. For the longest time i thought it was just because im pregnant {[18 weeks]}, but its getting worse. its happening more often. I get so dizzy it makes my head & neck hurt. What do you think this could be. My boyfriend is telling me i need to go to the hospital, or do you think its just the pregnancy? I really don't wanna go up there and have them tell me there is nothing wrong with me. Im really tierd of them telling me that when i go up there.

Somtimes it feels like my chest is tightening. But it always go away after a few min. But i know there is somthing more wrong then just my pregnancy!
